Martin Storsjö	0a14fefd68	movenc: Indicate that negative timestamps are supported The mov/mp4 muxer has support for handling negative timestamps via edit lists (which customarily is used for handling the 1-frame delay due to B-frames as well). Using the muxer's native way of handling it is better than using the generic offsetting. The generic offsetting is a bit too crude when e.g. the timebase of one track is 1/fps, where the edit lists can handle it accurately. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Stephen Hutchinson	2c25e83b1d	avisynth: Support video input from AviSynth 2.5 properly. Uses the 2.5 compatibility header included with the variant of FFMS2 that uses AviSynth's C-interface. A copy of this header is now provided in compat/avisynth. avs_get_row_size_p and avs_get_height_p changed between versions 2.5 and 2.6. Since the avisynth_c.h header that avformat uses assumes AviSynth 2.6, it would cause 2.5 to crash if given any kind of real video (the Version() function was known to work, though). AvxSynth was unaffected by this issue because, despite being based on AviSynth 2.5.8 and using 2.5.8's interface version number of 3, it actually uses 2.6's versions of these functions.

Carl Eugen Hoyos	9d86bfc259	hlsenc: Don't reset the number variable when wrapping The counter itself shouldn't be wrapped, since it is used for determining end_pts for the next segment - only wrap the number used for the segment file name.

Alexander Strasser	dc2e4c2e53	lavf/wavdec: Fix seeking in files with unaligned offsets A file with a prepended ID3 tag of an uneven length was found in the wild.

Martin Storsjö	b56fc18b20	sdp: Add an option for sending RTCP packets to the source of the last packets An SDP description normally only contains the target IP address and port for the packets. This means that we don't really have any clue where to send the RTCP RR packets - previously they're sent to the destination IP written in the SDP (at the same port), which rarely is the actual peer. And if the source for the packets is on a different port than the destination, it's never correct. With a new option, we can choose to send the packets to the address that the latest packet on each socket arrived from. --- Some may even argue that this should be the default - perhaps, but I'd rather keep it optional at first. Additionally, I'm not sure if sending RTCP RR directly back to the source is desireable for e.g. multicast. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	6b58e11a83	rtpproto: Add an option for writing return packets to the address of the last received packets If we've received packets on the same socket before, the return packets are sent to that address.

Mark Harris	4ccafaca1c	avformat/id3v2enc: use UTF-16 in id3v2.3 APIC frame only if non-ASCII This makes the encoding of picture descriptions consistent with the encoding of other text id3 tags and works better with iTunes, which does not display pictures with some UTF-16 picture descriptions (including a UTF-16 empty string, i.e. BOM + terminator). It also saves a few bytes. Example: ffmpeg -f lavfi -i sine=b=4 -f lavfi -i smptebars -map 0:a -map 1:v \ -codec:a libmp3lame -codec:v mjpeg -id3v2_version 3 \ -metadata:s:v comment="Cover (front)" -t 3 -y out.mp3 This example does not set a picture description (-metadata:s:v title=) so an empty string is written in the id3v2.3 APIC frame. Without this patch, UTF-16 is used and the cover art does not display in iTunes. With the patch the cover art is displayed. (Note that iTunes does not display or have a way to set picture descriptions, only the picture itself, but nevertheless has trouble skipping some UTF-16 descriptions.)
