• FFMPEG libraries : Bitstream "h264_mp4toannexb" filter does not work

  25 décembre 2013, par user2677612

  We are using FFmpeg libraries git-ee94362 libavformat v55.2.100. Our purpose is to mux two streams (video and audio) into M3U8 playlist using HLS.

  We are using AV_CODEC_ID_H264 output encoder, AV_PIX_FMT_YUV420P output video pixel format and CODEC_FLAG_GLOBAL_HEADER flag for the encoder.

  The last causes us to use "h264_mp4toannexb" bit stream filter.

  So, here is the code snippet :

  AVPacket outpkt = {0};
  
  int isGotVideoPacket = 0;
  
  
  
  av_init_packet(&outpkt);
  
  
  
  out_video_frame->pts = (int64_t) (video_frame_count * in_video_frame_duration / av_q2d(out_video_stream->time_base));
  
  
  
  int ret = avcodec_encode_video2(enc_out_video_ctx, &outpkt, out_video_frame[i], &isGotVideoPacket);
  
  
  
  assert(0 <= ret);
  
  
  
  if ((1 == isGotVideoPacket) && (0 < outpkt.size)) {
  
  
  
       AVPacket new_outpkt = outpkt;
  
  
  
       if ((AVBitStreamFilterContext*) 0 != vbsf_ctx) {
  
            AVPacket new_outpkt = outpkt;
  
  
  
             ret = av_bitstream_filter_filter(vbsf_ctx, enc_out_video_ctx, (const char*)0, &new_outpkt.data, &new_outpkt.size, outpkt.data, outpkt.size, outpkt.flags & AV_PKT_FLAG_KEY);
  
  
  
             if (ret > 0)
  
             {
  
                outpkt = new_outpkt;
  
             }
  
             else 
  
             {
  
                // We get ret = -22
  
                char errbuf[128] = ""; 
  
  
  
                // Both the functions get "Error number -22 occurred" that don't explain anything
  
                av_strerror (ret, errbuf, 128);
  
                av_make_error_string (errbuf, 128, ret);          
  
              }
  
  
  
              assert(0 <= ret);
  
  
  
       }
  
  
  
       outpkt->stream_index = output_video_stream->index;
  
  
  
       // If to comment av_bitstream_filter_filter() and "if-else", then
  
       // At frame #37 we get the following error from av_interleaved_write_frame():
  
       // [mpegts @ 09628140] H.264 bitstream malformed, no startcode found, use the h264_mp4toannexb bitstream filter (-bsf h264_mp4toannexb).
  
       ret = av_interleaved_write_frame(ofmt_ctx, &outpkt);
  
  
  
       assert(0 <= ret);                          
  
   }

  Our questions :

  1. What is the meaning of the "-22" error from av_bitstream_filter_filter()?
  
  2. Where can we get full FFMPEG error code description list?
  
  3. If we are using av_bitstream_filter_filter() right? If no, what is the right way?

• ffmpeg 1.0.7 takes minute to create a thumbnail on "broken" video file but other files are seconds to create thumbnail

  8 juillet 2015, par Wiggler Jtag

  I’ve been using ffmpeg 1.0.7 for over 450GB (cca 400 files) for creating thumbnails and grabbing video-file information. It tooks me like 1-2 seconds to create 10 thumbnails from 8GB file. But now I’ve got some ’broken’ video file (672 MB) which creates me 1 thumbnail over a minute, 10 thumbnails its over 10 minutes -> my server burns :

   PID USER      PR  NI  VIRT  RES  SHR S  %CPU %MEM    TIME+  COMMAND
  
   9769 www-data  20   0  395m  28m 7212 R 157.0  0.4   0:04.99 ffmpeg

  I opened the file in Windows Media Player and getting blank screen while -> video file is weird, opened it in VLC and it wrote me : Because this AVI file index is broken or missing, seeking will not work correctly. VLC won't repair your file but can temporary fix this problem by building an index in memory. I’ve clicked ’Play as is’ and it plays the video file correctly, however my webserver burns because of FFmpeg and PHP waits for the return from exec(); command. Thumbnails are also created fine after 10 minutes, but how can I fix this problem or to prevent from executing FFmpeg for creating thumbnails on these broken ’video’ files ?

  This is my php :

  $cmd = "ffmpeg -i error.avi 2>&1";
  
  $info = `$cmd`;
  
  echo '<pre>';
  
  print_r($info);
  
  echo '</pre>';

  this is the output I am getting (very quickly)

  So it looks like just creating thumbnails is having problems :

  exec("ffmpeg -ss 01:11:43 -i error.avi -vframes 1 -s 616x320 -an output_1.jpg 2>&1");

  Where could be the problem ? Thanks for your suggestions !

  Btw. I am posting this on SO because I’m not sure where it belongs more than here - I think it could be done somehow by PHP but I’m not really sure.

  EDIT : I have added timeout, which "fixes" my problem, but even latest version of FFmpeg 2. stucks on creating thumbnail from broken video files.

  exec("timeout 5s ffmpeg -ss 01:11:43 -i error.avi -vframes 1 -s 616x320 -an output_1.jpg 2>&1");
