• Join videos with different lengths (time) side by side with ffmpeg [duplicate]

  17 avril 2020, par Glaucio Rocha

  I have two mp4 videos of a video conference, with different sizes (duration).

  



  I need to join these videos side by side, keeping the conversation in sync.

  



  How can I do this with ffmpeg ? Remember that one video has a longer duration (time) than the other.

  



  Thanks !

• 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 :

I am using ffmpeg for decoding H.264 video in iOS platform, when running the following function :

  



  avcodec_send_packet(_codecCtx, &_packet)


  



  I got this error :

  



  "Thread 5" EXC_BAD_ACCESS(code =1, address = 0x6))
