[FFmpeg-devel] [PATCH] allow to call rm_read_audio_stream_info() with NULL AVFormatcontext

[Ronald S. Bultje]

Hi,

a while ago, I submitted patches to make RDT (RTSP/realmedia) work in
ffmpeg. Here's split-up small patches to make it work, most of it is just
rmdec re-arranging and such to call relevant code from a new rtp_rm.c file
such that I don't have to reimplement the rm-specific code in RTP.

this patch - rmdec-allownulls.patch - allows rm_read_audio_stream_info() to
be called with a NULL AVFormatContext, which is needed (before making it
non-static - later patch) to call it from the rtp_rm.c file. If s is NULL,
we don't want to store the strings in it, but just skip them. This makes a
lot of sense for RTP/realmedia anyway, since the metadata is already
transmitted in the SDP.
