[FFmpeg-devel] [PATCH 1/2] avcodec/bsf: Check side data when setting BSF EOF flag.

[sebechlebskyjan at gmail.com]

From: Jan Sebechlebsky <sebechlebskyjan at gmail.com>

Set BSF EOF flag only if pkt == NULL or both data and
side data are not present in packet.

 I believe that side data should be checked too, and 
 EOF flag set only when both data and side data are
 not present.

 I was testing new list BSF API I was working on,
 and with simple pass-though (empty list) BSF filter,
 some tests were failing because packets containing only
 side data were taken as EOF signal for bitsteam filter. 

 Also, I've added comment about this behaviour in next
 patch.
