[FFmpeg-devel] [PATCH v2 8/8] avformat/utils: Remove unnecessary initializations

[Andreas Rheinhardt]

Up until now, read_frame_internal always initialized the packet it
received. But since the recent changes to ff_read_packet, this is no
longer needed: If the parsing queue is initially empty upon entering
read_frame_internal, the packet will now either contain content upon
success or be blank upon failure of ff_read_packet. If the parsing
queue is initially not empty, the packet will be overwritten with the
oldest one from the parsing queue.

Similarly, it is unnecessary to initialize ret.
