FFmpeg merge two files from different sources with different bitrates
2 mars 2023, par FamousWollufI have created an intro video with Adobe Premiere Pro and I want to add the intro video to my downloaded Mixer stream videos before uploading them to YouTube, without reencoding the complete video through Adobe Premiere because that takes a long time because the videos are more then an hour.



I tried it with FFmpeg
ffmpeg -safe 0 -f concat -i list.txt -c copy output.mp4
.
The intro is normal but the video part from Mixer is running way to fast.

I think it has something todo with the bitrate but I can't figure it out.


Output of intro file :

If I need to reencode something my preference would be the intro because it's only 6 seconds.

ffmpeg HE-AAC 'unsupported codec' despite being compiled with support
12 mai 2020, par SebastianLack of default support of AAC for ffmpeg is really annoying :



My ffmpeg version :

I have several segment.ts files in
edit.txt
and I try to concatenate and convert to mpg :
ffmpeg -f concat -i edit.txt -c copy output.mpg



this does not work



Input #0, concat, from 'edit.txt':

Like DVD, VCD or others, make sure you set the correct buffer size
[mpeg @ 0x7f8e44807e00] Unsupported audio codec. Must be one of mp1, mp2, mp3, 16-bit pcm_dvd, pcm_s16be, ac3 or dts.
Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument
Error initializing output stream 0:1 --
Conversion failed!




so I tried with
ffmpeg -f concat -i edit.txt -c:v copy -c:a libfdk_aac output.mpg
-> same effect.


Why fraunhoffer codec exists and is mentioned on FFMPEG site if it is not supported ?
Is it any way to do this ?
