  • ffmpeg What's the difference between -to and -t options?

    - by Vantuz
    Command ffmpeg -ss 5:09 -i foo.mkv -to 5:10 -c copy bar.mkv works exactly like ffmpeg -ss 5:09 -i foo.mkv -t 5:10 -c copy bar.mkv Is it a bug?

  • FFMPEG based Theora Video Decoder performance??

    - by goldenmean
    Hi, I am in process of porting and optimization of the theora video decoder in the ffmpeg-0.5 package to ARM-Cortex-A8 -Neon processor @ 667 MHz. I am looking for some target estimate for frames per second the decoder library alone should achieve after full optimization (C level and Neon assembly / Intrinsics) for 720x480 Progressive content for a 2Mbps stream. I have a Real Video 9 decoder on cortex-A8 which gives around 40 fps for the same stream above.(720x480, 2Mbps) How can i extrapolate this data based on relative complexities of RV9 and Theora and get a fps estimate for theora decoder Cortex-A8? I am aware the performance depends upon the cache configuration of the h/w, etc...,but any Any pointers will help. Thanks, -AD

  • Making a DVD video with a still image and PCM 16bit audio with ffmpeg

    - by João
    I'm trying to make a small video with a still image and a sound file playing in the background to pass it to dvdauthor and create a DVD. The command I'm using is this: ffmpeg -loop_input -i image.jpg -qscale 2 -i song.flac -aspect 4:3 -target pal-dvd -acodec pcm_s16le -shortest output.mpg However, the resulting video file doesn't have sound at all (testing it on VLC Player). I don't know if I can't combine "-acodec pcm_s16le" with "-target pal-dvd" to override the later, or if there is something else wrong with the command. If I try without the "-acodec pcm_s16le" parameter the video and audio works, I can even create a DVD ISO with it. However, the audio stays as AC3. I wanted to include with the video the lossless audio, not a compressed one. I suppose the DVD standart allows to have PCM audio in it, am I right?

  • FFmpeg + iPhone - Interesting (incorrect?) video encoding results

    - by jtrim
    I'm encoding some video on the iPhone by running the png image data through swscale to get YUV420P data then encoding that frame using the MSMPEG4V1 codec. In the api docs, avcodec_encode_video should return the number of bytes used from the output buffer by that encode operation. There are 234,000 bytes going into the encoder, but the result returned by avcodec_encode_video is simply "4". The result is exactly the same over 24 frames. Something seems fishy here...any insight? Here's a pastebin link to the code: http://pastebin.com/ht94FWva (sorry for the link away from SO, I just didn't want to have the code duplicated in several places) EDIT: Also, I've set up a custom log callback for ffmpeg to use and I have the log level set to "Verbose" (libavutil/log.h), so libavcodec should be logging any goofs to the console, but avcodec is quiet throught he whole operation. (note: I did test to make sure my log callback was working)

  • Executing ffmpeg from php running in apache

    - by foobar
    I was executing ffmpeg from php running inside apache. I used to get the error " error while loading shared libraries: libavdevice.so.52: cannot open shared object file: No such file or directory". It used to work perfectly if the php script was executed from the command prompt or ffpmeg was directly invoked from the command prompt. I followed the below steps to fix the apache error: Step 1: Check if the file “libavdevice.so.52? exists in the server using the following command. find / -name ‘libavdevice.so.*’ Step 2: You will get the directory in which the file “libavdevice.so.52? exists from the above command. Suppose the directory is “/usr/local/lib/” in this example. Step 3: You have to add the directory name in the file “/etc/ld.so.conf”. Step 4: Execute the command “ldconfig”. How did doing the above make a difference to apache?

  • ffmpeg(libavcodec). memory leaks in avcodec_encode_video

    - by gavlig
    I'm trying to transcode a video with help of libavcodec. On transcoding big video files(hour or more) i get huge memory leaks in avcodec_encode_video. I have tried to debug it, but with different video files different functions produce leaks, i have got a little bit confused about that :). [Here] (http://stackoverflow.com/questions/4201481/ffmpeg-with-qt-memory-leak) is the same issue that i have, but i have no idea how did that person solve it. QtFFmpegwrapper seems to do the same i do(or i missed something). my method is lower. I took care about aFrame and aPacket outside with av_free and av_free_packet. int Videocut::encode( AVStream *anOutputStream, AVFrame *aFrame, AVPacket *aPacket ) { AVCodecContext *outputCodec = anOutputStream->codec; if (!anOutputStream || !aFrame || !aPacket) { return 1; /* NOTREACHED */ } uint8_t * buffer = (uint8_t *)malloc( sizeof(uint8_t) * _DefaultEncodeBufferSize ); if (NULL == buffer) { return 2; /* NOTREACHED */ } int packetSize = avcodec_encode_video( outputCodec, buffer, _DefaultEncodeBufferSize, aFrame ); if (packetSize < 0) { free(buffer); return 1; /* NOTREACHED */ } aPacket->data = buffer; aPacket->size = packetSize; return 0; }

  • iphone encode problem with ffmpeg

    Hi, I need to encode a video from image. I use ffmpeg and compiling rigth. My problem is that when i try to opne video with quicktime on iphone, this give me a message "this movie format is not supported". I create a file mp4 with this parameter on context: context-time_base.num = 1; context-time_base.den = 15; context-codec_type = CODEC_TYPE_VIDEO; context-codec_id = CODEC_ID_H264; context-bit_rate = 1000000; context-width = width; context-height = height; context-keyint_min = 10; context-i_quant_factor = 0.71; context-bit_rate_tolerance = 20000; context-rc_max_rate = 100000; context-rc_buffer_size = 8835000; context-qcompress = 0.6; context-qmin = 10; context-qmax = 30; context-max_qdiff = 4; context-gop_size = 30; context->time_base.num = 1; context-time_base.den = 30; context-sample_aspect_ratio = av_d2q(1, 255); context-profile = 30; context-pix_fmt = PIX_FMT_YUV420P; context-flags |= CODEC_FLAG_LOOP_FILTER; where is my mistake?? thanks

  • g++ Linking Error on Mac while compiling FFMPEG

    g++ on Snow Leopard is throwing linking errors on the following piece of code test.cpp #include <iostream> using namespace std; #include <libavcodec/avcodec.h> // required headers #include <libavformat/avformat.h> int main(int argc, char**argv) { av_register_all(); // offending library call return 0; } When I try to compile this using the following command g++ test.cpp -I/usr/local/include -L/usr/local/lib \ -lavcodec -lavformat -lavutil -lz -lm -o test I get the error Undefined symbols: "av_register_all()", referenced from: _main in ccUD1ueX.o ld: symbol(s) not found collect2: ld returned 1 exit status Interestingly, if I have an equivalent c code, test.c #include <stdio.h> #include <libavcodec/avcodec.h> #include <libavformat/avformat.h> int main(int argc, char**argv) { av_register_all(); return 0; } gcc compiles it just fine gcc test.c -I/usr/local/include -L/usr/local/lib \ -lavcodec -lavformat -lavutil -lz -lm -o test I am using Mac OS X 10.6.5 $ g++ --version i686-apple-darwin10-g++-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5664) $ gcc --version i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5664) FFMPEG's libavcodec, libavformat etc. are C libraries and I have built them on my machine like thus: ./configure --enable-gpl --enable-pthreads --enable-shared \ --disable-doc --enable-libx264 make && sudo make install As one would expect, libavformat indeed contains the symbol av_register_all $ nm /usr/local/lib/libavformat.a | grep av_register_all 0000000000000000 T _av_register_all 00000000000089b0 S _av_register_all.eh I am inclined to believe g++ and gcc have different views of the libraries on my machine. g++ is not able to pick up the right libraries. Any clue?

  • OpenCV install problems on Studio 12.04 - broken dependencies

    - by Will
    I'm trying to follow the Ubuntu OpenCV documentation at OpenCV. The provided script has a line which executed for some time, taking away more packages than I expected (such as ubuntu-studio video); sudo apt-get -qq remove ffmpeg x264 libx264-dev When the script gets to the line below, it bombs; sudo apt-get -qq install libopencv-dev build-essential checkinstall cmake pkg-config yasm libtiff4-dev libjpeg-dev libjasper-dev libavcodec-dev libavformat-dev libswscale-dev libdc1394-22-dev libxine-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libv4l-dev python-dev python-numpy libtbb-dev libqt4-dev libgtk2.0-dev libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev x264 v4l-utils ffmpeg The error msg is; E: Unable to correct problems, you have held broken packages. I've since run Update-Manager, run sudo apt-get updates, rebooted, tried the above script line manually, and still no change. I've just run sudo apt-get install -f and nothing seemed to change. It did mention that some packages were no longer needed and could be removed by apt-get autoremove, so I ran that. It removed a number of packages, so I reran the install command above. Still same problem of held broken packages. I just ran sudo apt-get -u dist-upgrade Part of the response was; The following packages have been kept back: gstreamer0.10-ffmpeg I'm not sure what that means. I do know that it shows up in my Update-Manager and cannot be checked I then ran sudo dpkg --configure -a and then reran sudo apt-get -f install and the package was still not upgraded, though there was this very interesting comment; Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: gstreamer0.10-ffmpeg : Depends: libavcodec53 (< 5:0) but it is not going to be installed or libavcodec-extra-53 (< 5:0) but 5:0.7.2-1ubuntu1+codecs1~oneiric2 is to be installed E: Unable to correct problems, you have held broken packages. Then I ran sudo apt-get -u dist-upgrade It showed I had one held package, so I ran; sudo apt-get -o Debug::pkgProblemResolver=yes dist-upgrade It also exited without upgrading the package, so I ran; sudo apt-get remove --dry-run gstreamer0.10-ffmpeg:i386 And it gave me; *The following packages will be REMOVED: arista gstreamer0.10-ffmpeg 0 upgraded, 0 newly installed, 2 to remove and 0 not upgraded. Remv arista [0.9.7-3ubuntu1] Remv gstreamer0.10-ffmpeg [0.10.12-1ubuntu1]* But when I reran sudo apt-get -u dist-upgrade It showed the package was still there. *The following packages have been kept back: gstreamer0.10-ffmpeg 0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.* Update: Just went into Synaptic PM and completely removed gstreamer0.10-ffmpeg Reran sudo apt-get -u dist-upgrade And was told; 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. However, when I ran the original apt-get to install opencv (first code at the top of this question), it still gave me the same broken package errors.

  • FFMPEG, FLAC. How do i encode with highest compression?

    - by acidzombie24
    With FFMPEG how do i encode a lossless codec (ATM i am testing with another flac) to a flac file with the highest compression level. With MediaMonkey i was able to compress to level 8 and i recompressed with ffmpeg and it matched the output of a level 6 compress. Even with -aq 8. How do i set it to the highest compression?

  • How do I use ffmpeg with live streaming from an IP camera

    - by Murali Hariharan
    My question is very basic because I am a newbie to all these technologies. I have an IP camera connected to my internal network. - "http://192.168.1.20/videostream.cgi?user=admin&pwd=" gives a live streaming view in Firefox or Internet Explorer. Now I want to record the live stream into a video. The parameters to be supplied are begin_time, end_time, format of video etc. How do I accomplish this? I appreciate any guidance. Thanks Murali

    I can easly upload video file to the server with SaveAs method. But when i wanted to convert video file to .flv file i can't see any output file in the folder that i expected to find. Actually i did it in my VS.NET 2008 IDE but after i published the files to the server, when i wrote the url of that internet site i couldn't see the files(in the remote machine i can see exported file and its converted file by calling http://localhost/FileUpload.aspx )

  • libav/ffmpeg: avcodec_decode_video2() returns -1 when separating demultiplexing and decoding

    - by unbekannt
    I'm using libav (from a C++ program on Linux and Windows) to decode video streams from a file, which works fine (decoding various formats like H264 and MPEG2) using avformat_open_input(), av_read_frame() and avcodec_decode_video2(). Now I have to separate demultiplexing and decoding. One class will call avformat_open_input() and av_read_frame() and then pass the AVPackets into a queue that is read by another class. There I use avcodec_alloc_context3() to get the AVCodecContext needed for avcodec_decode_video2(). I've tested that with a MPEG2 video stream and it works. Problems arise if I try to decode a H264 stream: avcodec_decode_video2() always returns -1 and outputs "no frame". I understand that additional data (SPS/PPS) is needed to decode this stream, so I've tried to replicate the original AVCodecContext from the demultiplexer in the decoder, but it won't work: Copying the content of the extradata field and setting all other values that differ from the default ones in the decoder: -1 is returned Using the same context (i.e. passing along the pointer) results in a crash I also tried to set CODEC_FLAG2_CHUNKS. avcodec_decode_video2() then always returns packet.size - 3 (??) and frameFinished is never set to 1. In my opinion I have a general problem here that will arise whenever settings from the original CodecContext are needed to decode the AVPackets. I'd be grateful for any hints on how to solve that problem!

  • How do you splice out a part of an xvid encoded avi file, with ffmpeg? (no problems with other files

  • ffmpeg: cut multiple input files with seeking to one output file

    - by Josef Kufner
    I have list of video files (loaded from database), each with start and end time of requested interval: # file begin end v1.mp4 1:01 2:01 v2.mp4 3:02 3:32 v3.mp4 2:03 5:23 And I need to create single video file containing these intervals: [0:00]---v1---[2:00]---v2---[2:30]---v3---[5:50] I preffer usig ffmpeg, since it is installed on server. Caller program is written in PHP. It is easy to cut one input to one output (argument escaping removed for clarity): exec("ffmpeg -ss $begin -i $input_file -ss $begin -c copy $output_file"); I there any easier way than executing ffmpeg for each interval and then execute it once more to concatenate prepared clips together? I really do not like to have a lot of temporary files or dealing with complex process handling.

Previously this worked perfectly. But now I'm stuck, and I've tried all revs between FFMPEG-PHP-0.5.1 - 0.6.1. Anyone that could think of what this could be?
