  • Streamed mp3 only plays for 1 second

    - by angel6
    Hi, I'm using the plaympeg.c (modified) code of smpeg as a media player. I've got ffserver running as a streaming server. I'm a streaming an mp3 file over http. But when I run plaympeg.c, it plays the streamed file only for a second. When I run plaympeg again, it starts off from where it left and plays for 1 second. Does anyone know why this happens an how to fix it? I've tested it out on WMP and it plays the entire file in one go. So, i guess it's not a problem with the streaming or ffserver.conf include include include include /* #ifdef unix */ include include include include include include include define NET_SUPPORT /* General network support */ define HTTP_SUPPORT /* HTTP support */ ifdef NET_SUPPORT include include include include endif include "smpeg.h" ifdef NET_SUPPORT int tcp_open(char * address, int port) { struct sockaddr_in stAddr; struct hostent * host; int sock; struct linger l; memset(&stAddr,0,sizeof(stAddr)); stAddr.sin_family = AF_INET ; stAddr.sin_port = htons(port); if((host = gethostbyname(address)) == NULL) return(0); stAddr.sin_addr = *((struct in_addr *) host-h_addr_list[0]) ; if((sock = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP)) < 0) return(0); l.l_onoff = 1; l.l_linger = 5; if(setsockopt(sock, SOL_SOCKET, SO_LINGER, (char*) &l, sizeof(l)) < 0) return(0); if(connect(sock, (struct sockaddr *) &stAddr, sizeof(stAddr)) < 0) return(0); return(sock); } ifdef HTTP_SUPPORT int http_open(char * arg) { char * host; int port; char * request; int tcp_sock; char http_request[1024]; char c; printf("\nin http_open passed parameter = %s\n",arg); /* Check for URL syntax */ if(strncmp(arg, "http://", strlen("http://"))) return(0); /* Parse URL */ port = 80; host = arg + strlen("http://"); if((request = strchr(host, '/')) == NULL) return(0); request++ = 0; if(strchr(host, ':') != NULL) / port is specified */ { port = atoi(strchr(host, ':') + 1); *strchr(host, ':') = 0; } /* Open a TCP socket */ if(!(tcp_sock = tcp_open(host, port))) { perror("http_open"); return(0); } /* Send HTTP GET request */ sprintf(http_request, "GET /%s HTTP/1.0\r\n" "User-Agent: Mozilla/2.0 (Win95; I)\r\n" "Pragma: no-cache\r\n" "Host: %s\r\n" "Accept: /\r\n" "\r\n", request, host); send(tcp_sock, http_request, strlen(http_request), 0); /* Parse server reply */ do read(tcp_sock, &c, sizeof(char)); while(c != ' '); read(tcp_sock, http_request, 4*sizeof(char)); http_request[4] = 0; if(strcmp(http_request, "200 ")) { fprintf(stderr, "http_open: "); do { read(tcp_sock, &c, sizeof(char)); fprintf(stderr, "%c", c); } while(c != '\r'); fprintf(stderr, "\n"); return(0); } return(tcp_sock); } endif endif void update(SDL_Surface *screen, Sint32 x, Sint32 y, Uint32 w, Uint32 h) { if ( screen-flags & SDL_DOUBLEBUF ) { SDL_Flip(screen); } } /* Flag telling the UI that the movie or song should be skipped */ int done; void next_movie(int sig) { done = 1; } int main(int argc, char *argv[]) { int use_audio, use_video; int fullscreen; int scalesize; int scale_width, scale_height; int loop_play; int i, pause; int volume; Uint32 seek; float skip; int bilinear_filtering; SDL_Surface *screen; SMPEG *mpeg; SMPEG_Info info; char *basefile; SDL_version sdlver; SMPEG_version smpegver; int fd; char buf[32]; int status; printf("\nchecking command line options "); /* Get the command line options */ use_audio = 1; use_video = 1; fullscreen = 0; scalesize = 1; scale_width = 0; scale_height = 0; loop_play = 0; volume = 100; seek = 0; skip = 0; bilinear_filtering = 0; fd = 0; for ( i=1; argv[i] && (argv[i][0] == '-') && (argv[i][1] != 0); ++i ) { if ( strcmp(argv[i], "--fullscreen") == 0 ) { fullscreen = 1; } else if ((strcmp(argv[i], "--seek") == 0)||(strcmp(argv[i], "-S") == 0)) { ++i; if ( argv[i] ) { seek = atol(argv[i]); } } else if ((strcmp(argv[i], "--volume") == 0)||(strcmp(argv[i], "-v") == 0)) { ++i; if (i >= argc) { fprintf(stderr, "Please specify volume when using --volume or -v\n"); return(1); } if ( argv[i] ) { volume = atoi(argv[i]); } if ( ( volume < 0 ) || ( volume 100 ) ) { fprintf(stderr, "Volume must be between 0 and 100\n"); volume = 100; } } else { fprintf(stderr, "Warning: Unknown option: %s\n", argv[i]); } } printf("\nuse video = %d, use audio = %d\n",use_video, use_audio); printf("\ngoing to check input parameters\n"); if defined(linux) || defined(FreeBSD) /* Plaympeg doesn't need a mouse */ putenv("SDL_NOMOUSE=1"); endif /* Play the mpeg files!

  • Why my application ask for a codec to pla the MVI(.MOV) video files while i can play them on WMP and QuickTime?

    - by Daniel Lip
    I have an application i did some time ago when im loading the video file its ok when trying to play/use the file im getting the messageBox message say that its need a codec to use gspot or search the internet. Wehn im playing this files on my hard disk with Windows Media Play or either QuickTime there is no problems. The Video files for example name are: MVI_2483 in the file name properties i see its type: Quick Time Movie (.MOV) In my application im using DirectShowLib-2005.dll this is the class im using in my case to extract the video file im using it in my application to extract only lightnings from the video file name. In Form1 i have a button click event that just starting the action: private void button8_Click(object sender, EventArgs e) { viewToolStripMenuItem.Enabled = false; fileToolStripMenuItem.Enabled = false; button2.Enabled = false; label14.Visible = false; label15.Visible = false; label21.Visible = false; label22.Visible = false; label24.Visible = false; label25.Visible = false; ExtractAutomatic = true; DirectoryInfo info = new DirectoryInfo(_videoFile); string dirName = info.Name; automaticModeDirectory = dirName + "_Automatic"; subDirectoryName = _outputDir + "\\" + automaticModeDirectory; if (secondPass == true) { Start(true); } Start(false); } This is the function start in Form1: private void Start(bool secondpass) { setpicture(-1); if (Directory.Exists(_outputDir) && secondpass == false) { } else { Directory.CreateDirectory(_outputDir); } if (ExtractAutomatic == true) { string subDirectory_Automatic_Name = _outputDir + "\\" + automaticModeDirectory; Directory.CreateDirectory(subDirectory_Automatic_Name); f = new WmvAdapter(_videoFile, Path.Combine(subDirectory_Automatic_Name)); } else { string subDirectory_Manual_Name; if (Directory.Exists(subDirectoryName)) { subDirectory_Manual_Name = subDirectoryName; f = new WmvAdapter(_videoFile, Path.Combine(subDirectory_Manual_Name)); } else { subDirectory_Manual_Name = _outputDir + "\\" + averagesListTextFileDirectory + "_Manual"; Directory.CreateDirectory(subDirectory_Manual_Name); f = new WmvAdapter(_videoFile, Path.Combine(subDirectory_Manual_Name)); } } button1.Enabled = false; f.Secondpass = secondpass; f.FramesToSave = _fts; f.FrameCountAvailable += new WmvAdapter.FrameCountEventHandler(f_FrameCountAvailable); f.StatusChanged += new WmvAdapter.EventHandler(f_StatusChanged); f.ProgressChanged += new WmvAdapter.ProgressEventHandler(f_ProgressChanged); this.Text = "Processing Please Wait..."; label5.ForeColor = Color.Green; label5.Text = "Processing Please Wait"; button8.Enabled = false; button5.Enabled = false; label5.Visible = true; pictureBox1.Image = Lightnings_Extractor.Properties.Resources.Weather_Michmoret; Hrs = 0; //number of hours Min = 0; //number of Minutes Sec = 0; //number of Sec timeElapsed = 0; label10.Text = "00:00:00"; label11.Visible = false; label12.Visible = false; label9.Visible = false; label8.Visible = false; this.button1.Enabled = false; myTrackPanelss1.trackBar1.Enabled = false; this.checkBox2.Enabled = false; this.checkBox1.Enabled = false; numericUpDown1.Enabled = false; timer1.Start(); label2.Text = ""; label1.Visible = true; label2.Visible = true; label3.Visible = true; label4.Visible = true; f.Start(); } And this is the class wich is not my oqn class i just just defined it in some places wich making the problem: using System; using System.Diagnostics; using System.Drawing; using System.Drawing.Imaging; using System.IO; using System.Runtime.InteropServices; using DirectShowLib; using System.Collections.Generic; using Extracting_Frames; using System.Windows.Forms; namespace Polkan.DataSource { internal class WmvAdapter : ISampleGrabberCB, IDisposable { #region Fields_Properties_and_Events bool dis = false; int count = 0; const string fileName = @"d:\histogramValues.dat"; private IFilterGraph2 _filterGraph; private IMediaControl _mediaCtrl; private IMediaEvent _mediaEvent; private int _width; private int _height; private readonly string _outFolder; private int _frameId; //better use a custom EventHandler that passes the results of the action to the subscriber. public delegate void EventHandler(object sender, EventArgs e); public event EventHandler StatusChanged; public delegate void FrameCountEventHandler(object sender, FrameCountEventArgs e); public event FrameCountEventHandler FrameCountAvailable; public delegate void ProgressEventHandler(object sender, ProgressEventArgs e); public event ProgressEventHandler ProgressChanged; private IMediaSeeking _mSeek; private long _duration = 0; private long _avgFrameTime = 0; //just save the averages to a List (not to fs) public List<double> AveragesList { get; set; } public List<long> histogramValuesList; public bool Secondpass { get; set; } public List<int> FramesToSave { get; set; } #endregion #region Constructors and Destructors public WmvAdapter(string file, string outFolder) { _outFolder = outFolder; try { SetupGraph(file); } catch { Dispose(); MessageBox.Show("A codec is required to load this video file.
