[FFmpeg-devel] [PATCH 1/6] lavc/codec2utils: Use actual libcodec2 version

[Tomas Härdin]

[-- Attachment #1: Type: text/plain, Size: 283 bytes --]

libcodec2 has reached 1.X so it's about time the bindings receive some
attention. This patchset also includes some much-needed tests. Where do
I submit files for inclusion in FATE again? They are very small as is
to be expected from a codec that runs at 700-3200 bit/s

/Tomas

[FFmpeg-devel] [PATCH 6/6] Add FATE tests for codec2, codec2raw and libcodec2 wrapper

[Tomas Härdin]

[-- Attachment #1: Type: text/plain, Size: 385 bytes --]

Tests all modes, both demuxers, the muxer, the decoder and the encoder.
Also tests both well-formed files and slightly broken truncated files

The raw files are just the .c2 files with the header stripped.
Therefore the relevant tests reuse the .c2 ref files.

I have attached all FATE files and, the source .wav file and the script
I used to generate all the files.

If they are the same, then can't you reuse the c2 files with the subfile
protocol for the raw tests? (This might necessitate some changes to
fate-run.sh, but it would provide coverage for the subfile protocol.)

I didn't know about the subfile protocol. But yeah seems like that
should be possible. I'll have a look

Updated patch attached. I also discovered some bugs in the previous
version

I'm thinking maybe not writing positions to the ref files. That way a
bunch of tests can share refs again

What version of libcodec2 are you using? I don't think we can rely on
versions that don't expose version information, which only comes about
because I explicitly told them to please expose it in a header. I don't
think we can even probe version at configure time otherwise.

libcodec2-dev on Debian bookworm works for me

i think theres no libcodec2* on the box and this header is used outside
checks for libcodec2* ...

Right, the demuxers and muxer can be used without having the library
installed. An #if CONFIG_LIBCODEC2 with a fallback to a fake version
should work. Given that 1.2.0 is the latest release that seems a
reasonable version to signal, indicating "1.2.0 was the last time we
checked that we're compatible with libcodec2"..
