  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • FFmpeg AVI to MP4 preserves sound, but not images [migrated]

    21 février 2013, par user1711384

    Working with FFmpeg at a conversion (any file to MP4 (H.264/AAC)) :

    ffmpeg -y -i testdatei.avi -i logo.jpg -filter_complex overlay=15:15,scale=-1:720 -c:v libx264 -profile:v baseline -preset medium -b:v 880k -g 10 -pass 1 -an -f mp4 -movflags faststart /dev/null
    
ffmpeg -y -i testdatei.avi -i logo.jpg -filter_complex overlay=15:15,scale=-1:720 -c:v libx264 -profile:v baseline -preset medium -b:v 880k -g 10 -pass 2 -c:a libfdk_aac -b:a 128k -movflags faststart xxx.mp4 2>&1

    With MPEG and WMV file it's working. With two different AVIs it didn't work. Logfiles from path 1 aren't generated and output 1 is empty, output 2 of course generates an error.

    After removing -profile:v baseline in both commands, the video file is successfully generated, but it's not possible to play it in JW Player (sound yes, but no image).

    This is the result of the first command :

    Do you have a idea why AVI makes problems ? What could be the solution ?

  • H.264 muxed to MP4 using libavformat not playing back

    14 mai 2015, par Brad Mitchell

    I am trying to mux H.264 data into a MP4 file. There appear to be no errors in saving this H.264 Annex B data out to an MP4 file, but the file fails to playback.

    I’ve done a binary comparison on the files and the issue seems to be somewhere in what is being written to the footer (trailer) of the MP4 file.

    I suspect it has to be something with the way the stream is being created or something.

    Init :

    AVOutputFormat* fmt = av_guess_format( 0, "out.mp4", 0 );
    
oc = avformat_alloc_context();
    
oc->oformat = fmt;
    
strcpy(oc->filename, filename);

    Part of this prototype app I have is creating a png file for each IFrame. So when the first IFrame is encountered, I create the video stream and write the av header etc :

    void addVideoStream(AVCodecContext* decoder)
    
{
    
    videoStream = av_new_stream(oc, 0);
    
    if (!videoStream)
    
    {
    
         cout << "ERROR creating video stream" << endl;
    
         return;        
    
    }
    
    vi = videoStream->index;    
    
    videoContext = videoStream->codec;      
    
    videoContext->codec_type = AVMEDIA_TYPE_VIDEO;
    
    videoContext->codec_id = decoder->codec_id;
    
    videoContext->bit_rate = 512000;
    
    videoContext->width = decoder->width;
    
    videoContext->height = decoder->height;
    
    videoContext->time_base.den = 25;
    
    videoContext->time_base.num = 1;    
    
    videoContext->gop_size = decoder->gop_size;
    
    videoContext->pix_fmt = decoder->pix_fmt;       
    

    
    if (oc->oformat->flags & AVFMT_GLOBALHEADER)
    
        videoContext->flags |= CODEC_FLAG_GLOBAL_HEADER;
    

    
    av_dump_format(oc, 0, filename, 1);
    

    
    if (!(oc->oformat->flags & AVFMT_NOFILE))
    
    {
    
        if (avio_open(&oc->pb, filename, AVIO_FLAG_WRITE) < 0) {
    
        cout << "Error opening file" << endl;
    
    }
    
    avformat_write_header(oc, NULL);
    
}

    I write packets out :

    unsigned char* data = block->getData();
    
unsigned char videoFrameType = data[4];
    
int dataLen = block->getDataLen();
    

    
// store pps
    
if (videoFrameType == 0x68)
    
{
    
    if (ppsFrame != NULL)
    
    {
    
        delete ppsFrame; ppsFrameLength = 0; ppsFrame = NULL;
    
    }
    
    ppsFrameLength = block->getDataLen();
    
    ppsFrame = new unsigned char[ppsFrameLength];
    
    memcpy(ppsFrame, block->getData(), ppsFrameLength);
    
}
    
else if (videoFrameType == 0x67)
    
{
    
    // sps
    
    if (spsFrame != NULL)

    Finally to close the file off :

    av_write_trailer(oc);
    
int i = 0;
    
for (i = 0; i < oc->nb_streams; i++)
    
{
    
    av_freep(&oc->streams[i]->codec);
    
    av_freep(&oc->streams[i]);      
    
}
    

    
if (!(oc->oformat->flags & AVFMT_NOFILE))
    
{
    
    avio_close(oc->pb);
    
}
    
av_free(oc);

    If I take the H.264 data alone and convert it :

    ffmpeg -i recording.h264 -vcodec copy recording.mp4

    All but the "footer" of the files are the same.

    Output from my program :
    readrec recording.tcp out.mp4
    ** START * 01-03-2013 14:26:01 180000
    Output #0, mp4, to ’out.mp4’ :
    Stream #0:0 : Video : h264, yuv420p, 352x288, q=2-31, 512 kb/s, 90k tbn, 25 tbc
    * END ** 01-03-2013 14:27:01 102000
    Wrote 1499 video frames.

    If I try to convert using ffmpeg the MP4 file created using CODE :

    ffmpeg -i out.mp4 -vcodec copy out2.mp4

out.mp4: could not find codec parameters

    I really do not know where the issue is, except it has to be something to do with the way the streams are being set up. I’ve looked at bits of code from where other people are doing a similar thing, and tried to use this advice in setting up the streams, but to no avail !

    The final code which gave me a H.264/AAC muxed (synced) file is as follows. First a bit of background information. The data is coming from an IP camera. The data is presented via a 3rd party API as video/audio packets. The video packets are presented as the RTP payload data (no header) and consist of NALU’s that are reconstructed and converted to H.264 video in Annex B format. AAC audio is presented as raw AAC and is converted to adts format to enable playback. These packets have been put into a bitstream format that allows the transmission of the timestamp (64 bit milliseconds since Jan 1 1970) along with a few other things.

    This is more or less a prototype and is not clean in any respects. It probably leaks bad. I do however, hope this helps anyone else out trying to achieve something similar to what I am.

    The stream stream/codecs are added and the header is created in a function called addVideoAndAudioStream(). This function is called from decodeIFrame() so there are a few assumptions (which aren’t necessarily good)
    1. A video packet comes first
    2. AAC is present

    The decodeIFrame was kind of a separate prototype by where I was creating a thumbnail for each I Frame. The code to generate thumbnails was from : https://gnunet.org/svn/Extractor/src/plugins/thumbnailffmpeg_extractor.c

    The decodeIFrame function passes an AVCodecContext into addVideoAudioStream :

    void addVideoAndAudioStream(AVCodecContext* decoder = NULL)
    
{
    
    videoStream = av_new_stream(oc, 0);
    
    if (!videoStream)
    
    {
    
        cout &lt;&lt; "ERROR creating video stream" &lt;&lt; endl;
    
        return;       
    
    }
    
    vi = videoStream->index;   
    
    videoContext = videoStream->codec;       
    
    videoContext->codec_type = AVMEDIA_TYPE_VIDEO;
    
    videoContext->codec_id = decoder->codec_id;
    
    videoContext->bit_rate = 512000;
    
    videoContext->width = decoder->width;
    
    videoContext->height = decoder->height;
    
    videoContext->time_base.den = 25;
    
    videoContext->time_base.num = 1;
    
    videoContext->gop_size = decoder->gop_size;
    
    videoContext->pix_fmt = decoder->pix_fmt;       
    

    
    audioStream = av_new_stream(oc, 1);
    
    if (!audioStream)
    
    {
    
        cout &lt;&lt; "ERROR creating audio stream" &lt;&lt; endl;
    
        return;
    
    }
    
    ai = audioStream->index;
    
    audioContext = audioStream->codec;
    
    audioContext->codec_type = AVMEDIA_TYPE_AUDIO;
    
    audioContext->codec_id = CODEC_ID_AAC;
    
    audioContext->bit_rate = 64000;
    
    audioContext->sample_rate = 16000;
    
    audioContext->channels = 1;
    

    
    if (oc->oformat->flags &amp; AVFMT_GLOBALHEADER)
    
    {
    
        videoContext->flags |= CODEC_FLAG_GLOBAL_HEADER;
    
        audioContext->flags |= CODEC_FLAG_GLOBAL_HEADER;
    
    }
    

    
    av_dump_format(oc, 0, filename, 1);
    

    
    if (!(oc->oformat->flags &amp; AVFMT_NOFILE))
    
    {
    
        if (avio_open(&amp;oc->pb, filename, AVIO_FLAG_WRITE) &lt; 0) {
    
            cout &lt;&lt; "Error opening file" &lt;&lt; endl;
    
        }
    
    }
    

    
    avformat_write_header(oc, NULL);
    
}

    As far as I can tell, a number of assumptions didn’t seem to matter, for example :
    1. Bit Rate. The actual video bit rate was 262k whereas I specified 512kbit
    2. AAC channels. I specified mono, although the actual output was Stereo from memory

    You would still need to know what the frame rate (time base) is for the video & audio.

    Contrary to a lot of other examples, when setting pts & dts on the video packets, it was not playable. I needed to know the time base (25fps) and then set the pts & dts according to that time base, i.e. first frame = 0 (PPS, SPS, I), second frame = 1 (intermediate frame, whatever its called ;)).

    AAC I also had to make the assumption that it was 16000 hz. 1024 samples per AAC packet (You can also have AAC @ 960 samples I think) to determine the audio "offset". I added this to the pts & dts. So the pts/dts are the sample number that it is to played back at. You also need to make sure that the duration of 1024 is set in the packet before writing also.

    I have found additionally today that Annex B isn’t really compatible with any other player so AVCC format should really be used.

    Problem to Decode H264 video over RTP with ffmpeg (libavcodec)
    http://aviadr1.blogspot.com.au/2010/05/h264-extradata-partially-explained-for.html

    When constructing the video stream, I filled out the extradata & extradata_size :

    // Extradata contains PPS &amp; SPS for AVCC format
    
int extradata_len = 8 + spsFrameLen-4 + 1 + 2 + ppsFrameLen-4;
    
videoContext->extradata = (uint8_t*)av_mallocz(extradata_len);
    
videoContext->extradata_size = extradata_len;
    
videoContext->extradata[0] = 0x01;
    
videoContext->extradata[1] = spsFrame[4+1];
    
videoContext->extradata[2] = spsFrame[4+2];
    
videoContext->extradata[3] = spsFrame[4+3];
    
videoContext->extradata[4] = 0xFC | 3;
    
videoContext->extradata[5] = 0xE0 | 1;
    
int tmp = spsFrameLen - 4;
    
videoContext->extradata[6] = (tmp >> 8) &amp; 0x00ff;
    
videoContext->extradata[7] = tmp &amp; 0x00ff;
    
int i = 0;
    
for (i=0;iextradata[8+i] = spsFrame[4+i];
    
videoContext->extradata[8+tmp] = 0x01;
    
int tmp2 = ppsFrameLen-4;   
    
videoContext->extradata[8+tmp+1] = (tmp2 >> 8) &amp; 0x00ff;
    
videoContext->extradata[8+tmp+2] = tmp2 &amp; 0x00ff;
    
for (i=0;iextradata[8+tmp+3+i] = ppsFrame[4+i];

    When writing out the frames, don’t prepend the SPS & PPS frames, just write out the I Frame & P frames. In addition, replace the Annex B start code contained in the first 4 bytes (0x00 0x00 0x00 0x01) with the size of the I/P frame.

  • No audio encoded with ffmpeg using webm/libvorbis

    15 mars 2013, par Craig Lillard

    Having issues getting audio to encode to webm. Tried many different methods and it just ain't happenin. The commands are printed below before each pass.

    I have tried moving the audio commands around, trying different bitrates, different audio commands and have tried it on a couple of different files as well that both have audio.

    Encoding these files to MP4 using x264 causes no problems and works just fine and the audio plays, so it appears to be an issue just with webm. As you can see below, it is a 2-pass encode.

    Thanks for any help you can provide !
