Vittorio Giovara	bb7701684c	lavf: Document the codec context initialization During remuxing avcodec_copy_context() is discouraged as certain fields (such as codec_tag) could reflect invalid values between input and output contextes.	10 years ago
wm4	9deaec7828	lavf: move internal fields from public to internal context This is not an API change; the fields were explicitly declared private before. Signed-off-by: Anton Khirnov <anton@khirnov.net>	10 years ago
Martin Storsjö	c4aa0f865f	libavformat: Remove a misleading/incorrect comment This comment can be traced back to the initial commit from 2001, and it seemed to be misleading/incorect already back then. (It was used for normal, non-raw file formats already then.) 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
Andreas Cadhalpun	b15b06ebf5	avformat: use const char* instead of uint8_t* for AVProbeData.mime_type This makes the field consistent with AVInputFormat.mime_type and the argument type of av_match_name. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Anton Khirnov	b263f8ffe7	lavf: add AVFormatContext.max_ts_probe It allows to configure how long will avformat_find_stream_info() wait to get the first timestamp.	10 years ago
Andrew Stone	afbd4b7e09	lavf: add AVFormatContext/AVStream fields for signaling to the user when events happen. The only flags, for now, indicate if metadata was updated and are set after each call to av_read_frame(). This comes with the caveat that, on stream start, it might not be set properly as packets might be buffered in AVFormatContext.packet_buffer before being given to the user in av_read_frame().

Luca Barbato	3a19405d57	avformat: Use the mime type information in input probe It should provide a quicker guess for elementary streams provided by http.	11 years ago
Diego Biurrun	7215fcf840	avformat: Mark AVOutputFormat argument in avformat_query_codec as const	11 years ago

Anton Khirnov	c9c1265c52	avformat: update muxing doxy The callers should now set the stream timebase, not the codec one.	11 years ago
Roman Savchenko	3d90f27ad5	avformat_new_stream: make the AVCodec parameter const Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Vittorio Giovara	cdab9db2ad	lavf: document av_dump_format()	11 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
Luca Barbato	6d212599aa	avformat: Provide a standard compliance flag Provide f_strict for avconv usage. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Janne Grunau	c23c96b638	lavf: add av_stream_get_side_data	11 years ago
Anton Khirnov	a312f71090	lavf: deprecate now unused AVStream.pts	11 years ago
Anton Khirnov	7a5f4f6853	lavf: extend avg_frame_rate documentation.	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	a738540366	lavf: properly document the distinction between flags and ctx_flags	11 years ago
Anton Khirnov	25b3258656	lavf: add an AVStream field for exporting stream-global side data	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	8b64c2ba03	lavc: add a dummy field to AVStream to preserve ABI compatibility for avconv avconv abuses the API by accessing AVStream.parser (which is private). Removing AVStream.reference_dts in `2ba68dd044` breaks ABI compatibility for an old avconv using a newer lavf. Fix this by adding a dummy field until the next bump.	11 years ago
Anton Khirnov	2ba68dd044	lavf: remove unreliable timestamp guessing heuristic	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
John Stebbins	26b241c079	matroskaenc: Allow chapters to be written in trailer This allows creation of frame accurate chapter marks from sources like DVD and BD where the precise chapter location is not known until the chapter mark has been reached during reading.
