Michael Niedermayer	a89c012531	avformat/mux: support shifting timestamps so they start at 0 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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.

Stefano Sabatini	5871ee5072	lavf: add output_ts_offset option to AVFormatContext This option can be generally useful to set an output offset, needed when setting an absolute index in the output.	11 years ago
James Darnley	86bee7984e	AVFormatContext: add metadata_header_padding field This field is used to store the number of bytes that should be written as padding to a metadata header of a file. For example: - The FLAC format's METADATA_BLOCK_PADDING [1] - The ID3v2 tag format's padding [2] [1] http://xiph.org/flac/format.html#metadata_block_padding [2] http://id3.org/id3v2.3.0#ID3v2_overview Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	2ef1e62c8d	correct the AVOption documentation for AV_EF_CAREFUL The flag was and is intended to be a sane default and thus does not enable time consuming checks. This also matches how the flag is used in decoders and demuxers. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Michael Niedermayer	7703d19c40	lavf/options_table: improve option help text Contains text suggested by carl Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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

Stefano Sabatini	d06ae0d791	lavf: fix documentation for avoid_negative_ts Prefer "non-negative" over "positive", the former is more accurate.	12 years ago
Timothy Gu	a9bbf59be7	cosmetics: Fix "dont" "wont" "doesnt" typos 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
Michael Niedermayer	a8e748eee5	lavf: add seek2any to allow forcing seeking to non keyframes via AVOptions Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Stefano Sabatini	98247e3368	lavf: clarify/extend documentation for AVFormatContext::analyzeduration "analyzeduration" is not used to detect the input duration, but to specify the max probe data duration. Fix option description and related doc entry accordingly.	12 years ago

Michael Niedermayer	28ff17fa97	lavf: add use_wallclock_as_timestamps This may fix Ticket730 Reviewed-by: Nicolas George <nicolas.george@normalesup.org> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Luca Barbato	681ed00099	avf: introduce nobuffer option Useful in cases where a significant analyzeduration is still needed, while minimizing buffering before output. An example is processing low-latency streams where all media types won't necessarily come in if the analyzeduration is small. Additional changes by Josh Allmann <joshua.allmann@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Alex Converse	40f81769ae	options_table: Add some missing #includes to fix "make checkheaders". Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Reimar Döffinger	a45605a1ba	Add AVIO_FLAG_DIRECT. Allows avoiding the buffer when using avio read, write and seek functions. When using the ffmpeg executable -avioflags direct can be used to enable this mode for input files, but has no effect on output files. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Martin Storsjö	4fa57d524f	libavformat: Set the default for the max_delay option to -1 Make the muxers/demuxers that use the field handle the default -1 in the same way as 0. This allows distinguishing an intentionally set 0 from the default value where the user hasn't set it. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Anton Khirnov	5626697104	Move AVFormatContext/AVCodecContext option tables to separate files. This will allow us to automatically generate manpages for them.	13 years ago

Michael Niedermayer	44d4fe9dad	error_detection: put the old error detection constants back. The old constants are more useful to the end user and have orthogonal meanings to the new ones. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Anton Khirnov	641c7afe3c	AVOptions: add new API for enumerating children. This will allow the caller to enumerate child contexts in a generic way and since the API is recursive, it also allows for deeper nesting (e.g. AVFormatContext->AVIOContext->URLContext) This will also allow the new setting/reading API to transparently apply to children contexts.	13 years ago
