• FFmpeg export codec not supported by Samsung

  21 juillet 2021, par Coski

  I am using FFmpeg to render videos (concatenating image files with audio and then applying speed and volume filters) to export videos to upload to TikTok. As a result, I must first move the videos to my phone.

  


  I do not understand why my phone (S20) will happily play one of the videos (codec information pictured first), but presents an error "Codec not supported" when playing the other (information second).

  


  

  


  

  


  The codec information is from VLC, and as you can see, both videos have identical Codecs (H264-MPEG4).

  


  From analysing the information, the only conclusion I come to is that it has something to do with the fact that the "Decoded Format" differs across the videos. How can I change my export command on the latter so my phone supports the codec ?

  


  CONCATENATION CODE
ffmpeg -f concat -safe 0 -i {path_temp}\\clips.txt -c copy -y "{path_temp}\\{title}_a.mp4

  


  FILTER CODE
ffmpeg -i input.mp4 -filter:a "volume={volume}" -y temp.mp4"

  


  SECOND FILTER
ffmpeg -i temp.mp4 -filter_complex "[0:v]setpts={1/speed}*PTS[v];[0:a]atempo={speed}[a]" -map "[v]" -map "[a]" -y output.mp4

  Error i got after run the code

  


  = RESTART: D:\Bots\2vidpod.py&#xA;Traceback (most recent call last):&#xA;  File "D:\Bots\2vidpod.py", line 71, in <module>&#xA;    os.remove(os.path.join(output_folder, &#x27;temp.mp4&#x27;))&#xA;FileNotFoundError: [WinError 2] Не удается найти указанный файл: &#x27;D:\\bots\\ttvidads\\VID\\ZAGOTOVKI\\Videopod1\\temp.mp4&#x27;&#xA;</module>

  


  so things i checked is
path is right
programs is installed FFMPEG and PYTHON all additional libraries downloaded
i pretty sure error caused by regular path and i wanna know if absolute path can do the thing

  I joined the unofficial ffmpeg discord server no one could find a fix I searched for ages and I couldn't fix it
