Audio Format NOT supported !

Maybe it would be better to try to figure out why ffmpeg is slower than ffmpeg.

Remuxing "Caras de la noticia ep1.ts"

ffmpeg started...

vs.

"F:\Hybrid\64bit\tsMuxeR.exe" "J:\tmp\tsmuxer_2023-11-20@14_52_48_2410_01_0.meta" "J:\tmp"
2023-11-20@14_52_48_2410_02_audio finished after 00:00:03.482
finished...

with:

MUXOPT --no-hdmv-descriptors --new-audio-pes --demux --vbr --vbv-len=500
A_MP3, "G:\clips\ts_remux_test\Caras de la noticia ep1.ts", track=482
A_MP3, "G:\clips\ts_remux_test\Caras de la noticia ep1.ts", track=483
A_AC3, "G:\clips\ts_remux_test\Caras de la noticia ep1.ts", track=484
A_AC3, "G:\clips\ts_remux_test\Caras de la noticia ep1.ts", track=485
V_MPEG4/ISO/AVC, "G:\clips\ts_remux_test\Caras de la noticia ep1.ts"

=> I suspect the thing that is slowing ffmpeg down is the bitstream filter
https://ffmpeg.org/ffmpeg-bitstream-filt...p4toannexb
(nowadays, that filter should even be added automatically: "Please note that this filter is auto-inserted for MPEG-TS (muxer mpegts) and raw H.264 (muxer h264) output formats. ")

Removing that from the call does not make a difference:

Neither does changing the thread count "-threads X" or removing the analysis/probe size "-analyzeduration 200M -probesize 200M".

adding "-vn -sn" to the audio extraction parts:

ffmpeg started...

does speed it up somewhat.

=> no clue why ffmpeg is so much slower than tsMuxeR
