I have just looked and found ffmpeg-4, will try that one.Please stop using antique versions....FFmpeg is currently on version 8.0, use that or at least any of the 7.x series if you want support. These ancient versions are often feature incomplete or even incompatible for today's codecs. They don't get updated, only the occasional bugfix (like correcting typo's in the documentation....)Also because of the fact that from version 7.0 the api has changed, breaking compatibility with older versions. Mostly since then, the speed has greatly increased (because of the new multithreading abilities) and support for modern codecs got a lot better.
I had no idea there was a version 8, now searching for it I see it.
As you say the api has changed, could you suggest a command line for doing the
conversion? Similar to:
ffmpeg -i movie.mkv \
-vf "scale=-1:802,format=yuv420p" -c:v libx264 -preset fast -crf 22 -tune
fastdecode -profile:v main -c:a copy -c:s copy \
output.mkv
but with 2 subtitle streams. I get audio not supported on VLC, and only one
subtittle stream. On version 3 and 4, same line gets working audio, and one
subtittle stream. Attempts to produce the two subtittles on version 4 killed
the audio.
Tried also this concoction suggested by chatgpt, VLC also refuses to play the
audio but generates the two subtittles:
ffmpeg -i movie.mkv -vf "scale=-1:802,format=yuv420p" -map 0 -c:v libx264
-preset fast -crf 22 -tune fastdecode -profile:v main -c:a aac -b:a 192k -c:s copy
-disposition:a:0 default 8c_movie.mkv
CLI outputs:
cer@Telcontar:/mnt/nfs/Isengard/xfsRaid/Videos/tmp> ffmpeg -t 10:0 -i movie.mkv -vf
"scale=-1:802,format=yuv420p" \
-c:v libx264 -preset fast -crf 22 -tune fastdecode -profile:v main \ -c:a copy -c:s copy -c:s copy 8_movie.mkv
