Fix CUVID crash on resolution change #418
Merged
Commits on Aug 19, 2024
-
ffmpeg: Flush filters before re-initialization.
Also add another condition for re-initialization: if the input resolution changes. This triggers the filter graph to re-build and adjust to the new resolution, when CPU encoders are in use.
-
-
ffmpeg: Reset the flush packet after each keyframe.
This handles cases where the packet may contain a frame that triggers a decoder reset - we do not want to cause a reset during the flushing process.
-
ffmpeg: Handle EAGAIN from decoder and drain
This usually happens with CUVID if the decoder needs to be reset internally for whatever reason, such as a mid-stream resolution change. Also block demuxing until decoder is ready to receive packets again.
