  • Other interesting software

    13 avril 2011, par

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...

  • How can I stream mjpeg file as rtsp

    24 août 2013, par Ilya Yevlampiev

    We have an mjpeg video, obtained from the webcam and stored into *.avi file, still encoded as mjpeg.

    We need to restream this file as rtsp (and stil preserve the mjpeg there, i.e. no decoding). The goal is to emulate the webcam this video was obtained from for the software that processes the video. The file can be open with vlc/ffplay with no problems. The ffmpeg behaves like it is streaming it, however, ffplay/vlc can't open this stream.

    We tried to stream if with gstreamer.

    1) we fount no free rtsp sink element for gstreamer pipeline. So, is there a free analogue for rtspsink to launch this pipeline with gst-launch ? we need and only cast, so we don't need so advanced element as rtspsink is.

    2) we also tried to build own simple rtsp server as described in http://weeklybuild.com/2013/01/creating-an-rtsp-stream-with-gstreamer/

    replacing videotestsrc with filesrc ; but what kind of elements we should use there ? usage of an only filesrc doesn't help ; we get the same problem as if we stream with ffmpeg. But what kind of lements we need there, if we dont' wan to decode/encode it, just to stream the file (to reproduce the thing what the webcam actually does).

  • How to write HEVC frames to file using FFMpeg ?

    2 mai 2018, par boneill

    I have the following code used to output H264 frames to an mp4 file and this works fine :

    typedef struct _AvFileStreamContext
    
{
    
    AVStream                 *pStreams[AV_FRAME_MAX];
    
    AVCodecContext           *streamCodec;
    
    AVFormatContext          *pAvContext;    // initialised with avformat_alloc_output_context2 for mp4 container
    

    
}_AvFileStreamContext;
    

    
static void WriteImageFrameToFile(const unsigned char * frame,
    
                                  const int frameSize,
    
                                  const struct timeval *frameTime,
    
                                  AvFileStreamContext *pContext,
    
                                  int keyFrame)
    
{
    
    AVStream *stream pContext->pStreams[AV_FRAME_VIDEO];
    
    AVPacket pkt;
    

    
    av_init_packet(&pkt);
    
    if (keyFrame)
    
    {
    
        pkt.flags |= AV_PKT_FLAG_KEY;
    
    }
    
    pkt.stream_index = stream->index;
    
    pkt.data = (unsigned char*)frame;
    
    pkt.size = frameSize;
    

    
    int ptsValue = round((float)( ( (frameTime->tv_sec - pContext->firstFrameTime.tv_sec ) * 1000000 +
    
                                    (frameTime->tv_usec - pContext->firstFrameTime.tv_usec)) * pContext->streamCodec->time_base.den ) / 1000000);
    

    
    // Packets PTS/DTS must be in Stream time-base units before writing so
    
    // rescaling between coder and stream time bases is required.
    
    pkt.pts =  av_rescale_q(ptsValue, pContext->streamCodec->time_base, stream->time_base);
    
    pkt.dts =  av_rescale_q(ptsValue, pContext->streamCodec->time_base, stream->time_base);
    

    
    av_interleaved_write_frame(pContext->pAvContext, &pkt);
    
}

    Once all frames have been received I call the following :

    av_write_trailer(pContext->pAvContext);
    
avio_close(pContext->pAvContext->pb);

    The above function is supplied from a circular buffer of frames where each entry in the buffer represents a frame for H264. I am trying to understand how I can adapt this to handle H265/HEVC frames. When I blindly try and use this for H265 frames I end up with an mp4 file where each frame only contains a third of a complete frame i.e.

    h265partialframe
    The video continues to play for the correct duration but each frame is only a third of a complete frame. The implementation for receiving frames is the same as H264 and it is my understanding that with H265 each of the buffers I am receiving represents a ’tile’. In my case these are tile columns of which 3 tiles make up one frame. That said, it would seem that the above function would need to be adapted to combine 3 tiles until an end of frame marker is received. I have trawled the FFMpeg v3.3 documentation to find out how I can achieve this but have had limited luck.
    I have tried to use the following function call to combine frames :

    uint8_t * outputBuffer;
    
unsigned int bufferSize;
    
stream->parser = av_parser_init (AV_CODEC_ID_HEVC);
    
int rc = av_parser_parse2(stream->parser, pContext->pAvContext,
    
                          &outputBuffer, &bufferSize,
    
                          frame, frameSize,
    
                          pkt.pts, pkt.dts, -1);

    It seems that the above call will ultimately call ;

    static int hevc_parse(AVCodecParserContext *s,
    
                      AVCodecContext *avctx,
    
                      const uint8_t **poutbuf, int *poutbuf_size,
    
                      const uint8_t *buf, int buf_size)

    Followed by :

    int ff_combine_frame(ParseContext *pc, int next,
    
                     const uint8_t **buf, int *buf_size)

    So it seems this is the correct path, however when I plug this all in the resulting mp4 file is not playable under gstreamer with the following errors :

    Prerolling...
    
(gst-play-1.0:11225): GStreamer-WARNING **: gstpad.c:4943:store_sticky_event: Sticky event misordering, got 'segment' before 'caps'
    
Redistribute latency...
    

    
(gst-play-1.0:11225): GStreamer-WARNING **: gstpad.c:4943:store_sticky_event: Sticky event misordering, got 'segment' before 'caps'

    And I get the following errors (snippet of errors) from VLC where the frames appear to be correct in terms of height and width but are corrupt or incomplete during playback :

    Here is an example frame from the VLC playback where you can just about see the outline of someone :
    h265combinedtiles

    It should be noted that when using the call to av_parser_parse2(), a frame is only passed to av_interleaved_write_frame() when outputBuffer is populated which seems to take a number of tiles (greater than 3) so I am possibly not setting something correctly.

    • Can I tell FFMpeg that a particular tile is an end of frame ?
    • Should I be using some other FFMpeg call to combine H265 tiles ?
    • Am I misunderstanding how HEVC operates ? (probably)
    • Once combined it the call to av_interleaved_write_frame() still valid ?
    • Note that use of libx265 is not possible.

    Any help appreciated.
