• Issue with audio codec in ffmpeg

  13 juillet 2021, par bloodstar

  To my little knowledge i believe this is an audio codec issue however since im not really familiar with ffmpeg, anything could be wrong.

  


    W:\PICTURES\\Manual Files>ffmpeg -i "C7984.mp4" -c copy -map 0 -segment_time 00:06:00 -f segment -reset_timestamps 1 C7984%03d.mp4

  Should the code be changed to convert the audio to flac prior to convert the clip ? thanks

  ffmpeg -i Downloads\Manifest.mpd


  


  After just 2 seconds it stops. This is the log :

  So basically, it did nothing. I have libxml2 installed and I am confused since there is no error at all. Any help ? Thank you !
