6294d708b8 rtsp: Only set the ttl parameter if the server actually gave a value
Passing ttl=0 to the rtp/udp url contexts makes packets never

c700fdb00f udp: Only bind to the multicast address if in read-only mode
This fixes sending back RTCP RR packets if receiving RTP over
multicast.

If the multicast stream is sent on demand (set up and signalled
via RTSP), the sender might depend on getting RTCP RR packets
knowing that there are listeners, otherwise the stream can be
closed after a certain timeout.

This fixes receiving RTSP streams over multicast on unix, from
certain Axis cameras.

between the existing comment and the existing line of code, making
the old comment seem to refer to the new code. This makes it read

19e72e0a8d Fix 32bit sunrast decoding.
This patch visually breaks the sample from ticket #895,
but decodes it identically as Gimp, ImageMagick and xview.

12623a8026 vorbisdec: avoid invalid memory access
This fixes some invalid memory access caused later in the function
by res_chan[] not being set for all channels. This happens when a
channel doesn't appear a submap. This change simply returns a
decoder error when this situation is detected.

ef0d779706 Fix uninitialized reads on malformed ogg files.
The ogg decoder wasn't padding the input buffer with the appropriate
FF_INPUT_BUFFER_PADDING_SIZE bytes. Which led to uninitialized reads in
various pieces of parsing code when they thought they had more data than
they actually did.

4ffe5e2aa5 huffyuv: add padding to classic (v1) huffman tables.
We slightly overread the input buffer, so we require
padding at the end of the buffer, as is documented in the
get_bits API. Without padding, we'll read uninitialized
data or beyond the end of the .rodata, which may crash.

Once fixed, the end_frame function does exactly what
avfilter_default_end_frame does; therefore, end_frame
can be removed to let avfilter_default_end_frame work.
