• SOLVED ffmpeg : consider increasing probesize error, but it is never satisfied

  27 octobre 2020, par Jaz

  I was trying to use an Arch solution for streaming to twitch today through FFMPEG, but all of my attempts were in vain because of one simple thing on FFMPEG. it says that the probesize is not large enough, so I instinctively increased the probesize value more and more... and now it is -probesize "500M" yet it is still saying it is not enough. here is the code snippet

  


  [x11grab @ 0x5631f846cd00] Stream #0: not enough frames to estimate rate; consider increasing probesize
Input #0, x11grab, from ':0.0':
  Duration: N/A, start: 1603397505.341400, bitrate: 1007124 kb/s
    Stream #0:0: Video: rawvideo (BGR[0] / 0x524742), bgr0, 1366x768, 1007124 kb/s, 30 fps, 1000k tbr, 1000k tbn, 1000k tbc
0: Input/output error


  


  and the code

  


  #!/bin/bash
     INRES="1366x768" # input resolution
     OUTRES="1366x768" # output resolution
     FPS="30" # target FPS
     GOP="60" # i-frame interval, should be double of FPS,
     GOPMIN="30" # min i-frame interval, should be equal to fps,
     THREADS="2" # max 6
     CBR="1000k" # constant bitrate (should be between 1000k - 3000k)
     QUALITY="ultrafast"  # one of the many FFMPEG preset
     AUDIO_RATE="44100"
     PROBESZ="500M" # specify a size for the ffmpeg tool to assess frames
     STREAM_KEY="$1" # paste the stream key after calling stream_now
     SERVER="live-mia" # twitch server in miami Florida, see https://stream.twitch.tv/ingests/ for list

     ffmpeg -f x11grab -s "$INRES" -r "$FPS" -i :0.0 -f pulse -i 0 -f flv -ac 2 -ar $AUDIO_RATE \
       -vcodec libx264 -g $GOP -keyint_min $GOPMIN -b:v $CBR -minrate $CBR -maxrate $CBR -pix_fmt yuv420p\
       -s $OUTRES -preset $QUALITY -tune film -acodec aac -threads $THREADS -strict normal \
       -bufsize $CBR -probesize $PROBESZ "rtmp://$SERVER.twitch.tv/app/$STREAM_KEY"


  


  even though it was a solution to store in .bashrc, I stored it in a script to call manually.

  


  and if this is helpful, here is the fancy banner ffmpeg shows before the error

• Chromecast HLS : Unable to derive timescale

  31 juillet 2020, par Scott

  I'm trying to get fmp4 HLS playing back on a new Chromecast (3rd gen I believe, not Ultra).

  


  I've tried encoding the content with ffmpeg using both x264 and h264 libraries.
The main profile initially gives me a codec not supported error, remove the codec list from the hls manifest fixes this issue.

  


  Switching to baseline (which is not ideal) doesn't give the codec error.

  


  Both then (after removing the codec definitions or using baseline) give the following error :
