Martin Storsjö	9257692ac1	lavf: Only initialize s->offset once when using avoid_negative_ts make_zero When given a stream starting at dts=0, it would previously consider s->offset as uninitialized and set an offset when the second packet was written, ending up writing two packets with dts=0. By initializing this field to AV_NOPTS_VALUE, we make sure that we only initialize it once, on the first packet. Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
Michael Niedermayer	897d5c3a42	lavf: Print a warning if failed to avoid negative timestamps when requested Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
Michael Niedermayer	1384df6419	lavf: Add an option for avoiding negative timestamps This is the same logic as is invoked on AVFMT_TS_NEGATIVE, but which can be enabled manually, or can be enabled in muxers which only need it in certain conditions. Also allow using the same mechanism to force streams to start at 0. Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago

Luca Barbato	eb4f906900	lavf: More informative error message Print the timestamp values and not just the stream index.	10 years ago

Anton Khirnov	194be1f43e	lavf: switch to AVStream.time_base as the hint for the muxer timebase Previously, AVStream.codec.time_base was used for that purpose, which was quite confusing for the callers. This change also opens the path for removing AVStream.codec. The change in the lavf-mkv test is due to the native timebase (1/1000) being used instead of the default one (1/90000), so the packets are now sent to the crc muxer in the same order in which they are demuxed (previously some of them got reordered because of inexact timestamp conversion).	11 years ago

Anton Khirnov	ed7922faac	mux: drop one of the hacks comprising compute_pkt_fields2() All encoders should output proper timestamps now.	11 years ago
Anton Khirnov	c9281a01b7	lavf: drop the zero-sized packets hack There should not be any valid reason anymore for passing completely empty packets to lavf. OTOH side data-only packets can be useful.	11 years ago
Anton Khirnov	0c1959b056	lavf: add AVFMT_FLAG_BITEXACT. Use it instead of checking CODEC_FLAG_BITEXACT in the first stream's codec context. Using codec options inside lavf is fragile and can easily break when the muxing codec context is not the encoding context.	11 years ago
Anton Khirnov	394fb56c29	lavf: always unref the packet passed to av_interleaved_write_frame() on error	11 years ago
Luca Barbato	d9ae1031f5	lavf: improve handling of sparse streams when muxing Currently ff_interleave_packet_per_dts() waits until it gets a frame for each stream before outputting packets in interleaved order. Sparse streams (i.e. streams with much fewer packets than the other streams, like subtitles or audio with DTX) tend to add up latency and in specific cases end up allocating a large amount of memory. Emit the top packet from the packet_buffer if it has a time delta larger than a specified threshold. Original report of the issue and initial proposed solution by mus.svz@gmail.com.

Anton Khirnov	33c859c142	lavf: ignore attachment streams for interleaving purposes Those streams should never get any packets by definition.	11 years ago
Anton Khirnov	7b03b65bf0	lavf: do basic sanity checking on muxed packets Reject packets for non-existing or attachment streams.	11 years ago
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

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.
