• FFmpeg warning : could not find codec parameters for stream 1 [closed]

  17 avril 2020, par Mocchi

  Hello : I have videos in the TS container that are Advanced Video Codec created by Elgato Game Capture HD60 Pro. I am trying to convert the TS videos because sometimes the Elgato MP4 output videos have audio/video sync issues. I have been trying for a few days now to get a clean remuxed video into MP4. I am using this simple batch file :

  



  ffmpeg -analyzeduration 10000M -probesize 10000000M -i "Game Video.ts" -acodec copy -vcodec copy "Game Video.mp4"
pause


  



  I always get these warnings no matter what I have tried. even if I use the -vn command to ignore the video. which makes me believe FFmpeg is seeing something or can't read something in my source video. The Source video Information via Media Info is here, there is 12 Audio streams which are all the same and I only put the first two here :

  I have not been able to figure out how to address the FFmpeg warnings and I am concerned that there is something wrong with the video that I will not find out until after I delete the source video. Any help is appreciated. here is the output from FFmpeg :

  Do I need to tell FFmpeg more information about the source file which I have seen suggested but I have been unable to implement. Again all Help is appreciated

  


• MP4 Created Using FFmpeg API Can't Be Played in Media Players

  11 avril 2020, par RandyCroucher

  I've been struggling with this issue for days. There are similar issues posted here and around the web, but none of the solutions seem to work for me. They are possibly outdated ?

  



  Here is the current iteration of code I'm using to generate the MP4 file.

  



  It generates a simple 2 second .mp4 file that fails to play in any player I've tried. If I run that mp4 file back through the FFmpeg command line, it will generate a perfectly playable movie out of it. So the data is there.

  



  Also, if you modify the output file name in this code from .mp4 to .avi, this code generates a playable avi file too. So whatever it is, it is tied to the H.264 format.

  



  I'm sure I'm missing something simple, but for the life of me, I can't figure out what that is.

  



  Any help would be greatly appreciated !

  Without adding the AV_CODEC_FLAG_GLOBAL_HEADER flag, I get a clean output from ffprobe, but the video still doesn't play. Notice it thinks the frame rate is 30.51, I'm not sure why.
