• Invalid data found in the last hls segment after transcoding

  28 février 2024, par GalaDOS

  When I use ffmpeg to transcode some pure audio flv files to hls segments, the last .ts segment contains some decoding errors. It seems that it happens when the last segment's duration is short enough (about 1.5 second).

  



  Here is my transcode command :

  



  ffmpeg -i 111.flv -c:a aac -b:a 128k -f hls -hls_time 10.00 -hls_list_size 9999 tmp.m3u8


  



  And output :

  After transcoding, the duration of the last segment in m3u8 file is 1.39 second :

  But when I use ffprobe to parse the last segment, I got an error :

  The input flv :

  



  http://45.76.56.248/hls_transcode_fail.flv
md5sum: 4627bbb27bcb22c143ad4dfa47359650


  



  Since my statistic module relies on the output of ffprobe, this exception will cause the entire transcoding task to fail. My temporary solution is to skip the last segment which is too short in the statistics phase. But I need a more reasonable and robust way to fix or bypass this issue. Any suggestion will be appreciated.

  


• ffmpeg : video codec ansi not compatible with flv

  11 septembre 2018, par diatomym

  lets say i have 10 video files, encoded with the following command in ffmpeg

  ffmpeg -i input.mp4 -c:v libx264 -preset medium -maxrate 6000k -bufsize 6000k -vf "scale=1280:-1,format=yuv420p" -g 50 -c:a aac -b:a 128k -ac 2 -ar 44100 file.flv

  now that all files match in codec, what i want to do is stream all those files via RTMP. for that, I’ll need to create a concat list. i also want the stream to infinitely repeat those 10 files. to do all these things, I use this command :

  ffmpeg -threads 2 -re -fflags +genpts -stream_loop -1 -i mylist.txt -c copy -f flv rtmp://link.to/RTMP

  when doing that, I get the following error output :

   ffmpeg -threads 2 -re -fflags +genpts -stream_loop -1 -i mylist.txt -c copy -f flv rtmp://link.to/RTMP

  what am i doing wrong ? thanks for the help.

• FFMPEG No encoder found for codec id 8

  3 septembre 2018, par raspiboele

  I’m using a Raspberry Pi to restreem a (https) .m3u8 stream, to a local MJPEG-stream with FFMPEG.
  Becaus I have a Nest Cam / Nest Hello and I want to import that stream into my Fibaro Homecenter (Smarthome Basestation), but the Fibaro Homecenter only eats the MJPEG format. So I made a Raspberry Pi with FFMPEG to do the trick.

  This is my /etc/ffserver.conf file :

  As you can see, I get an error : no encoder found for codec id 8
  It is frutstrating me, because I’m looking for a solution for three days now. I can’t even find a list of encoders and the coresponding ID’s. Do I have to enable maybe something in the ./configure ?

  My target is to get a stream at : http://localhost:8090/test1.mjpg

  Can anyone help me please ?
