writing to flac fails #193

Closed daveriedstra closed 2 years ago

daveriedstra commented 2 years ago

Hi there -- seems that specifying a flac output with either -o or -ext will cause the program to fail.

Here's the invocation and the output running on a stereo wav file. It fails the same on a mono flac file but succeeds with no extension specified.

$  ffmpeg-normalize -pr qjackrcd-2022-11-08T20-18-19.wav -o $(date -I)-norm.flac

slhck commented 2 years ago

I updated the README with a section on this:

https://github.com/slhck/ffmpeg-normalize#could-not-write-header-for-output-file-error

The basic issue is that by default the PCM codec (pcm_s32le) is chosen (to avoid quality loss), but that does not work for FLAC containers. Choose the flac codec manually with -c:a flac.

I've also updated the code to give a clearer error message in that case:

➜ ffmpeg-normalize test/test.wav -o out.flac
ERROR: Output extension flac does not support PCM audio. Please choose a suitable audio codec with the -c:a option.
