• Manipulating one video into multi outputs with FFmpeg results in no audio in the last output

  27 octobre 2015, par my name is

  Using FFmpeg, I’m trying to do some filtering operations on one input video to scale it (out1), scale and trim it (out2).
  This is the command I’m using :

  ffmpeg -y \
  
  -i "Robotica_1080.mkv" \
  
  -filter_complex "[0:v]split=2[v1][v2]; \
  
  [v1]scale=640:360,setpts=PTS-STARTPTS[vout1]; \
  
  [v2]trim=10:15,scale=640:360,setpts=PTS-STARTPTS[vout2]; \
  
  [0:a]asplit=2[a1][a2]; \
  
  [a1]anull,asetpts=PTS-STARTPTS[aout1]; \
  
  [a2]atrim=10:15,asetpts=PTS-STARTPTS[aout2]; \
  
  [vout1][aout1]concat=n=1:v=1:a=1[out1]; \
  
  [vout2][aout2]concat=n=1:v=1:a=1[out2]" \
  
  -map "[out1]" "1.mp4" \
  
  -map "[out2]" "2.mp4" 

  1.mp4 is ok while 2.mp4 lasts 5 seconds as expected but without audio at all (the QuickTime inspector doesn’t write the audio codec)

  I tried to remove the trim/atrim filters, so the filter_complex parameter looked like this :

  -filter_complex "[0:v]split=2[v1][v2]; \
  
  [v1]scale=640:360[vout1]; \
  
  [v2]scale=640:360[vout2]; \
  
  [0:a]asplit=2[a1][a2]; \
  
  [a1]anull[aout1]; \
  
  [a2]anull[aout2]; \
  
  [vout1][aout1]concat=n=1:v=1:a=1[out1]; \
  
  [vout2][aout2]concat=n=1:v=1:a=1[out2]" \

  but still no audio on 2.mp4

  Can anyone give me a hint ?

  —EDIT—
  This is the output from first ffmpeg command :

• FFmpeg : HLS options cannot be set/get/find

  4 septembre 2013, par user2677612

  We are using FFmpeg libraries git-ee94362 libavformat v55.2.100.
  We are trying to write a simple HLS code example based on muxing.c standard one.
  Let be two input streams, video and audio (they can be synthetic, doesn't matter).
  Our purpose is to mux them into M3U8 playlist using HLS.
  Suppose, duration of every TS segment file be 3 sec, and the desirable maximum number of entries in M3U8 output file be 100.

  From the FFmpeg application sources, one can see that the Apple HTTP Live Streaming segmenter implemented in hlsenc.c file.
  And the relevant options there are, as well : "hls_list_size", "hls_time", etc.
  The problem is that we have not succeeded to set/get/find these options in a conventional way, as shown in the following code :

  ---

  // Here is a part of main() program
  
  
  
  int64_t i1 = 0;
  
  void *target_obj;
  
  
  
  AVFormatContext *ofmt_ctx = NULL;
  
  AVOutputFormat *ofmt = NULL;
  
  
  
  avformat_alloc_output_context2(&ofmt_ctx, NULL, NULL, "Example_Out.m3u8");
  
  
  
  ofmt = ofmt_ctx->oformat;
  
  
  
  // The relevant options ("hls_list_size", "hls_time") are located under ofmt->priv_class->option.
  
  // But AVClass *priv_class is not the first member of the AVOutputFormat.
  
  // So, due to the documentation, av_opt_find...(), av_opt_get...() and av_opt_set...() 
  
  // cannot be used for options within AVOutputFormat.
  
  // In practice, any of the following three lines causes exception.
  
  const AVOption *o = av_opt_find2(ofmt, "hls_list_size", NULL, 0, AV_OPT_SEARCH_CHILDREN, &target_obj);
  
  av_opt_get_int(ofmt, "hls_list_size", AV_OPT_SEARCH_CHILDREN, &i1);
  
  av_opt_set_int(ofmt, "hls_list_size", 10, AV_OPT_SEARCH_CHILDREN);

  ---

  Our question : If there is a way to overcome the problem, i.e. to set/get/find options for AVOutputFormat, like for AVCodecContext (for example) ?

  Thank you,

  Andrey Mochenov.

  Flexible support for various pattern searches

  Adds a few pattern searches to achieve various tradeoffs
  between motion estimation complexity and performance.
  The search framework is unified across these searches so that a
  common pattern search function is used for all. Besides it will
  be easier to experiment with various patterns or combinations
  thereof at different scales in the future.

  The new pattern search is multi-scale and is capable of using
  different patterns at different scales.

  The new hex search uses 8 points at the smallest scale
  and 6 points at other scales.
  Two other pattern searches - big-diamond and square are
  also added. Big diamond uses 4 points at the smallest scale and
  8 points in diamond shape at the larger scales.
  Square is very similar conceptually to the default n-step search
  but is somewhat faster since it keeps only one survivor across
  all scales.

  Psnr/speed-up results on derf300 :

  hex : -1.6% psnr%, 6-8% speed-up
  big-diamond : -0.96% psnr, 4-5% speedup
  square : -0.93% psnr, 4-5% speedup
