Bug: 2.4.1 and ffmpeg7.1 need issue #1586

Open Pro-pra opened 1 week ago

Pro-pra commented 1 week ago

Observed Behavior

On build stage this error:

decklink_producer.cpp:641:52: error: 'AVFilterLink' {aka 'struct AVFilterLink'} has no member named 'min_samples'
  641 |                     audio_filter_.sink->inputs[0]->min_samples = audio_cadence_[0];

Expected behaviour

In ffmpeg7 min_samples i see in libavfilter/filters.h but it is not installed by default https://github.com/FFmpeg/FFmpeg/blob/a5f0daf8433899d7d644523156ad1078301543f8/libavfilter/filters.h#L153

Ok, i patch ffmpeg7 and install libavfilter/filters.h

Also patch casparcg-server:
