• Could not find codec parameters for stream 0

  14 avril 2017, par khinester

  When I run this command :

  ffmpeg -y -i ./in.mp4 -c:v png -f image2pipe -thread_queue_size 1024 -r 25 -t 186.75 -i - -filter_complex overlay=0:0 -c:v libx264 -pix_fmt yuv420p -movflags +faststart ./out.mp4 < ./out.png

  I get an error :

• FFmpeg cannot find codec parameters for yuv420p stream

  4 avril 2017, par Shade

  I am trying to use FFmpeg (with IJKPlayer) to stream an RTSP stream from a camera. I am trying to do this on iOS, so I compiled FFmpeg by myself.

  However, when I try to play the stream, it seems to produce an error :

  Could not find codec parameters for stream 0 (Video : h264, 1 reference
  frame, none(left)) : unspecified size Consider increasing the value for
  the ’analyzeduration’ and ’probesize’ options

  Further down, the stream information displayed is as follows :

    Metadata:
  
      title           : streamed by the Santachi RTSP server
  
    Duration: N/A, start: 0.000000, bitrate: 64 kb/s
  
      Stream #0:0, 0, 1/90000: Video: h264, 1 reference frame, none(left), 90k tbr, 90k tbn, 180k tbc
  
      Stream #0:1, 0, 1/8000: Audio: pcm_alaw, 8000 Hz, 1 channels, s16, 64 kb/s

  For reference, when I try to connect to the stream from my PC, it works, and the stream info I get is as follows :

    Metadata:
  
      title           : streamed by the Santachi RTSP server
  
    Duration: N/A, start: 0.000000, bitrate: N/A
  
      Stream #0:0, 28, 1/90000: Video: h264 (Main), 1 reference frame, yuv420p(progressive, left), 1280x720, 0/1, 20 tbr, 90k tbn, 180k tbc
  
      Stream #0:1, 17, 1/8000: Audio: pcm_alaw, 8000 Hz, mono, s16, 64 kb/s

  Seeing that the codec is yuv420p, I recompiled FFmpeg with the following options included :

  COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --enable-decoder=yuv4"
  
  COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --enable-demuxer=yuv4mpegpipe"

  H264 decoder and parser are already enabled. However, the result was the same. Also, other streams, from different sources seem to work fine. It’s just this particular camera’s stream that doesn’t work.

  Since it seems that FFmpeg, when compiled correctly, can consume the stream, it seems that I am missing some options when compiling it, but I have no idea which options. Any help ?
