[FFmpeg-devel] [PATCH] increase SDP buffer size

[Ronald S. Bultje]

Hi,

I've found some streams with SDP lines longer than 1024 bytes.
Currently, rtsp.c discards those extra bytes, leading to incomplete
SDP parsing and failure to play/offer some streams (or offer them
incorrectly) in the RTSP client.

Attached patch detects those, adds an av_log(ERROR) so we can detect
when it happens (instead of silently losing data) and increases the
buffersize to handle the stream that failed for me like this:

[rtsp @ 0x1830800]Discarded 13 bytes of SDP line-data (OpaqueData)
[rtsp @ 0x1830800]Discarded 465 bytes of SDP line-data (ASMRuleBook)
