Missed Audio Codecs on Latest Build!

[jicomy]

hello and i hope you have good time

when i downloaded latest build of https://www.gyan.dev/ffmpeg/builds/ and i checked codecs and i found out that some of audio encoder not exist in your latest build

here a list of removed/missed codec that exist in other people builds but not in BtbN build (tested on Latest Auto-Build (2022-03-13 12:33) amr_wb Encoder gsm Encoder gsm_ms Encoder ilbc Encoder speex Encoder

[BtbN]

Are those external libraries? Everything that has a native de/encoder in ffmpeg should be enabled by default.

[jicomy]

yes, all of them using libraries, but thats not the point, because vorbis and mpeg3 using libraries too this codecs that i reported are exist in all of other peoples builds

[BtbN]

Yes, Vorbis and mp3 are also hugely popular, while these ones are ultra rare, so it's a tradeoff between maintenance work needed, increase in binary size, and increase in attack surface. Do you personally need any of those, or are you just comparing builds?

[jicomy]

yes, i need gsm_ms one when i change my ffmpeg.exe with this BtbN Build, i found out that something is wrong because i had it before now there is no such codec when i changed from gyan.dev build to BtbN build

[BtbN]

libgsm looks archaic, I'll see if I can get it working without too much trouble. It's packaged in basically all distros, so there's a bunch of examples to work with.

[jicomy]

its archaic, but some people, someday, at some place or corner will need them, however, if you enable all of missed libraries it will be great, because FFmpeg mainly used as an converter tool, however, it does much more maybe there is more codecs that their encoders are available in FFmpeg but not included in any build, enabling them will be great Thank you for Answering, Have Good time

[BtbN]

It very much depends on the library. Some of them don't play nice with modern compilers, OS, or static linking. Or are such a huge risk that it's not worth to enable. libgsm looks relatively fine though, just has a weird build system that needs to be dealt with somehow.

BtbN missing the following encoders: Hap libvo_amrwbenc libgsm libgsm_ms libilbc libshine libspeex While gyan missing libopenh264 libjxl
