2013-12-19ffmpeg: add backported AAC7.1 patch to patches directoryAnssi Hannula
2013-12-19[ffmpeg] - backport - avcodec/aacdec: default to non-wide 7.1 in non-strict modeAnssi Hannula
Upstream commit e10fccf62a36e09b54ad6ea3d5fa6638f298d5ae, for http://trac.xbmc.org/ticket/13758. AAC specification has 7.1(wide) as a default layout for 8-channel streams (channel config 7). However, at least Nero AAC encoder encodes non-wide 7.1 streams using the default channel config 7, mapping the side channels of the original audio stream to the second AAC_CHANNEL_FRONT pair in the AAC stream. Similarly, e.g. FAAD decodes the second AAC_CHANNEL_FRONT pair as side channels, therefore decoding the incorrect streams as if they were correct (and as the encoder intended). FFmpeg currently decodes such files by-the-spec, i.e. after decoding the original front pair will be in AV_CH_FRONT_x_OF_CENTER and the original side pair will be in AV_CH_FRONT_x. As actual intended 7.1(wide) streams are very rare while misencoded 7.1 files actually exist in the wild, default to assuming a 7.1 layout was intended unless in strict mode. Fixes playback of e.g. 8_Channel_ID.m4a in samples. Signed-off-by: Anssi Hannula <anssi.hannula@iki.fi> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
2013-12-15ffmpeg: add patch to stop find_stream info when all pmt's are foundJoakim Plate
2013-12-15mpegts: stop analyzing when pmt for all programs have been foundJoakim Plate
This disables NOHEADER after finding PMT for all programs to avoid find_stream_info always exhausting probe size for mpegts. This is very important for live streams since read speed will be limited. rtsp, udp and any protocol streaming a live mpegts will have dramatically faster startup time. Note, lack of codec parameters for streams can still cause the full probe size to be exhausted.

per packet The common case of the pointer having increased by one packet (which results in no change to the modulus) can be detected with a 64-bit subtraction, which is far cheaper than a division on many platforms.

2013-08-07[ffmpeg] - backport - mpegts: Make discard_pid() faster for single-program ↵Ben Avison
streams When a stream contains a single program, there's no point in doing a PID -> program lookup. Normally the one and only program isn't disabled, so no packets should be discarded.

2013-08-07[ffmpeg] - backport - mpegts: Remove one memcpy per packetBen Avison
This was being performed to ensure that a complete packet was held in contiguous memory, prior to parsing the packet. However, the source buffer is typically large enough that the packet was already contiguous, so it is beneficial to return the packet by reference in most cases.
