Can't record audio in PCM format

[slonkazoid]

When I try to record with -a -P pcm_s16le (or any other PCM format), it gives me an error saying

Failed to read from PulseAudio stream: Invalid argument

I can record with ffmpeg -f pulse -i default -c:a pcm_s16le test.mkv so it's not a ffmpeg issue.
It has no issue recording in opus.

This wouldn't be that big of a problem if there was an obvious way to specify audio bitrate

which version of wf-recorder are you using at the time?

Providing -P like you report seems to be incorrect, I get an error "Invalid codec option pcm_s16le". I think the -P param should be in the form of -P <option_name>=<option_value> (according to the man page).

Otherwise, can you also try running with wf-recorder --log <other params> to get more insights on what's happening.

Hope it helps!

0.4.1

yeah that seems to be a copy paste issue, it's supposed to be -a -C pcm_s16le

Otherwise, can you also try running with wf-recorder --log <other params> to get more insights on what's happening.

unfortunately did not provide me any info other than this:

Choosing sample format s16 for audio codec pcm_s16le
[SWR @ 0x77ff2442c3c0] Using fltp internally between filters

which ffmpeg should be able to handle just fine

Hope it helps!

thank you

flac seems to kinda work so i think ill use that, the cpu time cost is negligible
