  • Question About MP4(AAC) Binary Tree

    - by DeanMc
    I'm in the very early stages of working on a tag editor for mp4 files and more specifically iTunes AAC ones. After doing some snooping around it seems that the file's structure is not as complicated as I first thought and is built in a sort of tree like the following 4 Bytes [Atom Length] 4 Bytes [Atom Name] X Bytes [Atom Data] An atom's data is as large as the length and can contain either Data(information) or another atom. What I am trying to work out is how one determines if the data is information or an actual atom. Any insight would be much appreciated.

  • MP4 video plays on localhost but not after publish

    - by teahou
    I made a video using Camtasia Studio 8. I added it to my MVC App and ran it on local host, video plays fine. I publish to my local dev web server (windows server 2008), the video will not play. Gives no error. I have tried on chrome and IE11. On chrome I checked the network tab and it says "Status - Cancelled". Do I need to make some changes on the web server settings? <video width="320" height="240" controls="controls"> <source src="@Url.Content("~/Content/videos/3_Comments_Letters.mp4")" /> </video>

  • Why is the resulting file unplayable when I use FFMPEG to convert a MP4 video to ASF?

    - by Fuupoo
    I want to convert an .mp4 file to an .asf file, but I need to keep the size of the file below 150 mb (the server I need to upload the file to can only take files under 150 mb). Basically I want to recontain the .mp4 in an .asf file. The code I'm using currently is ffmpeg input.mp4 -c copy output.asf The command runs, however when I try to play the file on windows media player (I'm on windows xp) I get an error message saying "Windows media player has encountered a problem while playing the file." Anyone have any idea why this is happening? And what other ways I can accomplish this task?

  • How do I add another audio stream to an MP4 file?

    - by RandomEngy
    I've got an MP4 video file and I want to add another AAC audio track to it. I've tried YAMB and MeGUI (frontends for MP4Box) and it plays correctly in Zoom Player, but it picks the wrong track in WMP and plays both at once in Quicktime. I think this might have to do with designating the default audio track somehow. Does anyone know how to specify the default audio track with YAMB/MeGUI or know of another way of adding a track to an MP4 file?

  • What is the fastest and best way to convert an rmvb video to mp4/mkv without losing any quality?

    - by Eric Leung
    the file will be played in a popbox3d. my old method was to convert the video using vidcoder (an offshoot of handbrake) using normal settings, but i've recently confirmed that this significantly reduces video and audio quality. i bumped up the conversion quality to 'high profile' and this produced a higher quality video but raised the conversion time to about twice the video length (95 minutes to convert a 45 minute video) on a core2duo laptop. this is less than ideal when a large number of videos need to be converted. i have tried a direct remuxing using mkv toolnix but this produced a video that refused to display video on the popbox3d, which is consistent with the reported: [quote=other old thread] it is possible to put RealMedia A/V in MKV container (used MKVtoolnix) - however, it is awkward to play later. RV40 is only suspected to be based on H.264 - simplify, is not consistent with MPEG-4 AVC specification. [/quote] i have read that ... [quote=from old thread] Under normal circumstances, [ffmpeg] should convert the video to .video.mp4 and the audio to (.wav then to) .audio.mp4, then mux the video and audio into a new .mp4 file and delete the temporary video-only and audio-only files.[/quote] and i am currently attempting to discover how this is done. help? PS: i download a lot of series from asia and for some strange reason, rmvb is a really popular format over there. sometimes, it's the only format that's available. unfortunately, it's a format that is incompatible with the popbox3d, so i have to convert the files before i can watch them on my tv.

  • Enable H.264 (or x264) in AVIDemux

    - by Thomas
    I am trying to get AVIDemux set up with the X264 codec using this tutorial. The following is what goes down when I get to the ./configure --enable-mp4-output command Thomas-Phillipss-MacBook:x264 tomdabomb2u$ sudo ./configure --enable-mp4-output Password: Unknown option --enable-mp4-output, ignored Found no assembler Minimum version is yasm-0.6.2 If you really want to compile without asm, configure with --disable-asm. So I tried it. Thomas-Phillipss-MacBook:x264 tomdabomb2u$ sudo ./configure --enable-mp4-output --disable-asm Unknown option --enable-mp4-output, ignored Warning: gpac is too old, update to 2007-06-21 UTC or later Platform: X86_64 System: MACOSX asm: no avs: no lavf: no ffms: no gpac: no pthread: yes filters: crop select_every debug: no gprof: no PIC: no shared: no visualize: no bit depth: 8 You can run 'make' or 'make fprofiled' now. I issued make, and then Thomas-Phillipss-MacBook:x264 tomdabomb2u$ ./x264 -v -q 20 -o foreman.mp4 foreman_part_qcif.yuv 176x144. And as expected, the results are: x264 [error]: not compiled with MP4 output support So I'm stuck. Any ideas?

  • Compiling x264 with mp4 support problem

    - by johnas
    I'm trying to compile x264 with mp4 output support. I download the latest version from their git by typing git clone git://git.videolan.org/x264.git When I run ./configure it configures and I'm able to make it. But when i try to configure it with ./configure --enable-mp4-output and then try to make it, it returns a strange error, indicating that there is a compilation error. The error message looks like: ... Lots of similar errors ... output/mp4.c:297: warning: implicit declaration of function ‘gf_isom_add_sample’ output/mp4.c:297: error: ‘mp4_hnd_t’ has no member named ‘p_file’ output/mp4.c:297: error: ‘mp4_hnd_t’ has no member named ‘i_track’ output/mp4.c:297: error: ‘mp4_hnd_t’ has no member named ‘i_descidx’ output/mp4.c:297: error: ‘mp4_hnd_t’ has no member named ‘p_sample’ output/mp4.c:299: error: ‘mp4_hnd_t’ has no member named ‘p_sample’ output/mp4.c:300: error: ‘mp4_hnd_t’ has no member named ‘i_numframe’ I've tried different releases. I've installed gpac, ffmpeg, and tried numerous tips from the net. But still can't get it to work. The reason I want it with mp4 output is because I want to use ffmpeg to create mp4 files encoded with x264. I'm running Ubuntu Server 9.10 32 bits.

  • How to get netstream bytesLoaded and bytesTotal from streaming .mp4?

    - by Amy
    I have a flex 3 app that uses netstream and a video object to stream .mp4 movies. I want to use the bytesLoaded and bytesTotal properties of the netstream to display the buffering information. I would also like to get any information about the number of frames that are dropped if possible. When I've tested on .flv I'm able to get the information without a problem, but it doesn't seem to work on .mp4. Is it possible to get this information streaming .mp4? Is there some configuration that I'm missing to make things work the same for .mp4 as .flv? Thanks!

  • How to convert a video via ffmpeg to an mp4 format that will stream and/or download to iPhone and Bl

    - by Yegor
    I have a site where people upload videos, which are converted to .flv format. Simple. I wanted to also convert to an mp4 format that will "stream" to an iphone and blackberry, or allowed to be downloaded to either, for later viewing. Can someone post a working ffmpeg line to accomplish this task? Closest I got was this (which doesn't work) ffmpeg -i in.avi -f mp4 -vcodec libx264 -maxrate 1000 -qmin 3 -qmax 5 -bufsize 4096 -g 300 -acodec libfaac -s 480x320 -ab 128k -qscale 7 out.mp4

  • MP4 files show up but won't stream to xbox 360

    - by Greg
    I set up a basic media server to stream to my 360 using uShare. Here are the instructions I used: http://linuxexpresso.wordpress.com/2011/01/02/howto-ubuntu-upnp-server-to-xbox-360/. I can stream avi files fine but I cannot stream mp4s. When I go to videos on the xbox, I can see all of the videos and folders but when I click play for an mp4 nothing happens. On my ubuntu desktop I can click on the mp4 file and it plays fine. And if I take that file, stick it on a thumb drive and plug it directly into the xbox the mp4 will play off the thumb drive. I'm lost for why it won't work through ushare. Any ideas?

  • What is the best way to downscale mp4 video while keeping it as sharp as possible?

    - by Brandon Durham
    I've got an .mp4 file that's currently 830x1100 (it's a screencast) that I need to resize down to 114x150. I've been experimenting for hours with ffmpeg settings and nothing comes out looking nice and sharp. The original file looks decent, and I can't figure out why the downscaling makes it look so blurry. Unfortunately I can't share the video because it contains a walkthrough for software that hasn't yet been released.

  • Free Tool to let you burn an mp4 to a DVD that can be watched in a DVD player

    - by vaccano
    I am looking for a tool that will let me take an mp4 and burn it as a DVD (you know, the kind I can watch in my DVD player). I tried DVD Flick but when the DVD was done the audio was off by at least a full second. I saw this question: http://superuser.com/questions/89467/burning-a-mpg-fileaudiovideo-to-dvd-to-view-in-a-dvd-player But the tool mentioned there does not say it supports MP4s. Any one have any cool tools for this?

  • What is the best approach to embed mp4 for the iPhone without using JavaScript?

    - by usingtechnology
    I am trying to troubleshoot this code and am running into a dead-end, so I thought I would ask my first question here. I have three questions: 1) What is the best approach to embed an mp4 for an iPhone specific view, preferably without using Javascript? 2) Are there any preferred practices to debug code on an iPhone? 3) Can anyone tell me what is wrong with my specific code below? I should mention upfront that the variable $fileName does indeed contain the correct info, I've just omitted that portion of the code. Also, the poster image does flicker for a brief moment before I receive the greyed out, broken QuickTime image so that is an indication that this is partially working. Code: <object width="448" height="335" classid="clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B" codebase="http://www.apple.com/qtactivex/qtplugin.cab"> <param name="src" value="/libraries/images/$fileName.jpg" /> <param name="href" value="/libraries/media/$fileName.mp4" /> <param name="target" value="myself" /> <param name="controller" value="true" /> <param name="autoplay" value="false" /> <param name="scale" value="aspect" /> <embed src="/libraries/images/$fileName.jpg" href="/libraries/media/$fileName.mp4" type="video/mp4" target="myself" width="448" height="335" scale="aspect" controller="false" autoplay="false"> </embed> </object>

  • Convert DVD to MP4 / H.264 with HD Decrypter and Handbrake

    - by DigitalGeekery
    Are you looking for a way to convert your DVD collection to high quality MP4 files? Today we are going to take a look at using DVDFab HD Decrypter along with Handbrake to convert DVDs to MP4 using the H.264 codec.  Process Overview Handbrake is a great file conversion application, but it unfortunately can’t handle DVD copy protection. For that we will use DVDFab’s HD Decrypter. HD Decrypter is the always free portion of the DVDFab application. What HD Decrypter will do, is remove the copy protection from your DVD, and copy the Video-TS and Audio-TS folders to your hard drive. Once the copy protection is gone, we will use Handbrake to convert the files to MP4 format with H.264 compression. Note: You’ll get full access to all the options in DVDFab  during the 30 trial period. However, the HD Decrypter is free and will continue to work. Ripping the DVD Install both Handbrake and DVDFab HD Decrypter. (Download links below) Once the applications are installed, place your DVD into your DVD drive and open DVDFab. On the welcome screen, click “Start DVDFab.”   You’ll be prompted to choose your region. Click “OK.” The disc is analyzed and opened… You’ll be brought to the main interface. Make sure you have the Full Disc option selected at the left panel and “Copy DVD-Video (VIDEO_TS folder) is selected. Click “Start.” Don’t be confused by the “DVD to DVD” option pop up. We won’t actually be burning to DVD. The HD Decrypter portion of the DVDFab suite is part of the DVD to DVD option. Click “OK.” The DVD will be ripped to your hard drive. When the copy process is complete, you’ll be prompted to insert media to start the write process. We aren’t going to be burning to disc, so just click Cancel then close out of DVDFab.   Converting to MP4 Now we are ready to convert Open Handbrake and click on the “Source” button at the top left. Select DVD / VIDEO_TS folder from the drop down list. Now we need to browse for the location where DVDFab HD Decrypter copied your movie. By default, that location will be the \DVDFab\Temp\FullDisc directory in your Documents folder. For example, in Windows 7, it would be: C:\Users\%username%\Documents\DVDFab\Temp\FullDisc\[Name of Your DVD] Select the folder, and click “OK.” You may be prompted to set a default path in Handbrake. This is an optional step. Click “OK.” If you’d like to set a default destination folder, Go to Tools on the top menu, select Options. On the General tab, click “Browse” to select a destination output folder. Click “Close” when Finished.   Next, click the dropdown list next to “Title.” Select the title that matches the length of the movie. It’s possible you may have see more than one title with a similar length. If so, consult the DVD information, or a site like IMDB.com, to find the proper movie title length. Select your container under Output Settings. This will be your final output file extension. We will be using MP4 for this example. You also have the option of MKV.   If you didn’t set up a default destination folder, you’ll need to select one by clicking the “Browse” button. You can manually customize the output file name and change the output file extension to .mp4 (Unless you prefer the iPod friendly .m4v extension). Settings There are a variety of custom settings that can be changed either through the tabs listed under Output Settings, or by selecting one of the Presets to the right. If converting exclusively for any of the devices listed in the preset list, simply click on that device and the settings will be automatically applied in the Output Settings tabs. For more Universal (non-Apple) devices or output, select the Normal profile.   For the most part, the presets will suit quite nicely. However, you can further customize settings if you’d like. The Picture tab allows you to tweak the size or cropping region. You must change Anamorphic to Loose or Custom to change the size.   The Video tab allows you to choose your codec. H.264 is the default. You also have the option to choose a target (output) size. The Constant Quality is recommended to be set between 59% – 63%. Anything over 70% will likely result in an output file larger than the input without any improved quality. On the Subtitles tab, you can select an available subtitle from the dropdown list and click “Add” to add it to the output file. When you’ve finished any customizations you are ready to begin the conversion process. Click “Start.” A Command window will open and you can follow the process. You’ll probably want to find something to do in the meantime as the process could take a couple of hours. When the process completes, you’re ready to watch your video.   Although it’s a time consuming process that involves a couple steps, this method will give you high quality H.264 video files.

  • How to play .mp4 movies?

    - by Andrew
    I have a .mp4 movie (it's an .mp4 file, and the "video codec" is Xvid, and the "audio codec" is mp3) that I want to play, but when I try to open it in MPlayer, it says "The steam is encrypted and decryption is not supported." I tried to apply the answer from this question and this wiki page, but neither worked. Any suggestions? The file came from an [apparently] less than reputable site, which I guess I can't link to. :( I've tried: sudo apt-get install ubuntu-restricted-extras sudo apt-get install libdvdread4 sudo /usr/share/doc/libdvdread4/install-css.sh sudo apt-get install gstreamer0.10-ffmpeg sudo apt-get install w64codecs sudo apt-get update
