API Changed (in struct obs_encoder_info):
----------------------------------------
bool (*get_audio_info)(void *data, struct audio_convert_info *info);
bool (*get_video_info)(void *data, struct video_scale_info *info);
To:
----------------------------------------
void (*get_audio_info)(void *data, struct audio_convert_info *info);
void (*get_video_info)(void *data, struct video_scale_info *info);
The encoder video/audio information callbacks no longer need to manually
query the libobs video/audio information, that information is now passed
via the parameter, which the callbacks can modify.
The refactor that reduces boilerplate in the encoder video/audio
information callbacks also removes the need for their return values, so
change the return types to void.
This adds support for the AverMedia C985 encoder (which is available on
C985 capture cards) as well as the C353 hardware encoder (which is
currently available on the X99S Gaming 9 motherboards).
These encoders have some limitations, such as limited resolutions
(1280x720 and 1024x768), a max GOP size of 30, and the encoder format
only supports YV12, which requires conversion if the current output
format isn't the same. The C985 and C353 encoders seem to be pretty
much identical, although it seems like the C353 has a bit more efficient
encoding.
I don't believe these are really suitable for streaming, as they do not
really have the encoding efficiency needed to stream at lower bitrates,
and seem to only support variable bitrate. However, for recording these
encoders are quite nice to have available, and work quite well.
