[FFmpeg-devel] [PATCH v3 2/2] doc/examples/transcode_aac: Set decoder packet timebase

[FFmpeg-devel] [PATCH v3 2/2] doc/examples/transcode_aac: Set decoder packet timebase

[Andreas Unterweger]

Previously, the default timebase caused two warnings during decoding 
about not being able to update timestamps for skipped and discarded 
samples, respectively.
