Luca Barbato	596e5d4783	lavf: Add a flag to enable/disable per-packet flushing This is enabled by default and can be disabled with "-fflags -flush_packets". Inspired by a patch from Nicolas George <nicolas.george@normalesup.org>. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Diego Biurrun	7950e519bb	Disable deprecation warnings for cases where a replacement is available	12 years ago
Stefano Sabatini	08b99be7c4	lavf/mux: rename variable cortag -> tagbuf2 in init_muxer() Possibly enhance readibility.	12 years ago
Rafaël Carré	e21307a2b0	lavf: don't abort if both encoder and muxer aspect ratios are not set Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago
Luca Barbato	12db891dcd	avf: move ff_write_chained to mux.c	12 years ago
Vignesh Venkatasubramanian	98c292a7a8	Adding support for encoding VP8 Alpha This patch adds support for encoding VP8 files with alpha. The alpha channel is encoded separately and the output is placed in AVPacket's side_data. The muxer then muxes it into the BlockAdditional element of the matroska container.

Diego Biurrun	e926b5ceb1	avformat: Drop unnecessary ff_ name prefixes from static functions	12 years ago
Michael Niedermayer	ba323d67fa	avformat/write_packet: drop disabled code Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	eba33396f0	avformat/mux: set avoid_negative_ts based on flags if not overridden by user or muxer This changes the default to avoid negative timestamps. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	647f306b46	avformat/mux: assert that timestamps are positive after offsetting them Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	c329195a27	avformat/mux: use a local variable for offset Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	060f14f493	avformat/mux: change avoid_negative_ts code to support later addition of AVStreams Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Luca Barbato	c2cb01d418	lavf: introduce AVFMT_TS_NEGATIVE Most formats do not support negative timestamps, shift them to avoid unexpected behaviour and a number of bad crashes.

Michael Niedermayer	a286940da1	mux: also call avio_flush() when flushing the muxer Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Nicolas George	4f112a8e34	lavf/mux: add the flush_packets option. Note: a lot of muxers already do the flushing explicitly.	12 years ago
Anton Khirnov	32e5194969	lavf: remove disabled FF_API_INTERLEAVE_PACKET cruft	12 years ago
Anton Khirnov	1afddbe59e	avpacket: use AVBuffer to allow refcounting the packets. This will allow us to avoid copying the packets in many cases. This breaks ABI.	12 years ago
Michael Niedermayer	46730e7a0c	mux/chunked interleaver: better align duration chunks. This code causes the chunking to tend toward more optimal alignment between streams. The first chunks can still be less optimal aligned	12 years ago
Michael Niedermayer	69a96f9d4c	mux: de-obfuscate chunked interleaver checks Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	c57c1329a9	mux: simplify chunking interleaver code Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	1191db31c1	mux: fix chunked interleaver The code did not account properly for packets that where added to the end of the packet list. Also flags for such packets where not set correctly leading to incorrect chunked interleaving. Reported-by: bcoudurier Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	cae11e4031	mux: fix chunked_duration rounding anomaly a small value was rounded to 0 and then treated special as if chunked_duration was 0. This led to a inconsistency that further led to wrong interleaving Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	d641ee94b5	lavf: Fix assignments in if() Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	1ac5a8d7e3	lavf/mux: Fix assignments in if() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Clément Bœsch	119d70db50	lavf/mux: do not pass a copy of the packet to write_packet(). Sometimes the muxer modifies the packet, like for instance lavf/mp3enc changing pkt->destruct in order to keep a copy. These changes must be kept, even though the muxer behaviour is questionable. Regression since `0072116`. Fixes #2124.	12 years ago
Clément Bœsch	0072116ccb	lavf: split packets before muxing. After demuxing, data and side are merged. Before decoding, they are split. Encoder will perform with data and side split. This means that a muxer can receive split data (after encoding) but also merged data (if called directly after demuxing). This commit makes sure data and side are split for the muxer.	12 years ago
Michael Niedermayer	f2a7e1a62b	mux: change 1 assert->av_assert1() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	5e6439a125	ff_choose_timebase: only try factors upto 14 otherwise a unexpected timebase could be choosen that is one that is thousand times more precisse than requested which can have sideeffects. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	de707bc8bd	mux/nut: factorize ff_choose_timebase() out of nut Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Luca Barbato	1e46c63eb7	avformat: refactor avformat_write_header Split away option settings, sanity checks and general setup.	12 years ago
Luca Barbato	86bbdf865e	avformat: refactor avformat_write_header Mostly cosmetic changes adding some intermediate to shorten the lines.	12 years ago
Luca Barbato	55f9037f38	avformat: split muxing functions from util.c	12 years ago
