Michael Niedermayer	2e4ec8947d	lavf: fill in past dts based on reordered pts once the delay becomes known. Previously we had ignored the past dts and just filled in from the point where we have had sufficient information. This should fix Ticket1734 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	a8e3815db5	lavf: factorize timestamp shift in update_initial_timestamps() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	3ba0dab76a	lavf: Add support offset timestamps on muxing. This allows avoiding negative timestamps. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	299c0b30a6	lavf: fix bug that caused has_decode_delay_been_guessed() to never return !=0 Possibly fixes Ticket1724 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Duncan Salerno	4b80a619b7	Handle the following type of relative URL correctly: http://a/b + //c/d = http://c/d http://a/b?c + ?d = http://a/b?d http://a/b?c/d + /e = http://a/e Updated with feedback from Clément Bœsch Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Clément Bœsch	4390f8c28d	Fix two "skiping" typo.	12 years ago
Michael Niedermayer	6bcbe768bb	lavf: dont add apic streams for demuxers that dont support it. Fixes crash Fixes ticket1730 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Stefano Sabatini	bbe9fe469a	lavf/utils: remove loop on AVERROR(EAGAIN) in av_read_frame() The loop was introduced in `64d340c62a`, and was likely breaking non blocking reads as it busy loops.	12 years ago
Anton Khirnov	9eb296572e	lavf: use a malloced AVFrame in try_decode_frame(). This allows using avcodec_free_frame() to free it properly.	12 years ago
Stefano Sabatini	64d340c62a	lavf/utils: add error check in av_read_frame() In particular, fix crash when the input file contains no packets (e.g. an ffmeta input).	12 years ago
Michael Niedermayer	21c4393f1c	lavf/find_stream_info: make sure we decode at least one frame for DTS The channel layout at the demuxer layer is commonly wrong and would otherwise be used. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	61a84755a9	lavf: dont open a decoder at the top of find_stream_info before probing has finished It could open the wrong decoder. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	a380f82c53	lavf: allow using request_probe as a score threshold to accept a codec Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Anton Khirnov	1cc569ddda	lavf: zero data/size of the packet passed to read_packet().	12 years ago
Janne Grunau	6746cd7f61	lavf probe: prevent codec probe with no data at all seen This occurs with fuzzed mpeg-ts files. set_codec_from_probe_data() is called with a zeroed AVProbeData since no packet made through for specific stream.	12 years ago
Reimar Döffinger	07d2d06395	Remove code that duplicates existing code a few lines down. This also fixes a potential crash since s->pb can be NULL. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	12 years ago
Luca Barbato	3f7fd59d15	avformat: fix typo in avformat_close_input The condition should not be &&.	12 years ago
Anton Khirnov	3b4bb19e63	lavf: flush the output AVIOContext in av_write_trailer(). This is consistent with stdio and is what we want to do in all cases. Fixes a bug in the voc muxer which didn't flush in write_trailer() previously. This is the cause of the change in the test results.	12 years ago
Anton Khirnov	0c270239c2	lavf: cosmetics, reformat av_write_trailer().	12 years ago
Michael Niedermayer	e2d643efcd	lavf/compute_pkt_fields: only run pts by duration correction if reference ts is available Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Luca Barbato	44272c1ccc	avformat: refactor avformat_close_input Do not crash if the input format is not allocated yet.	12 years ago
Luca Barbato	4d1f443c3d	avformat: simplify avformat_close_input avio_close checks by itself for NULL condition.	12 years ago
Michael Niedermayer	062091f87f	compute_pkt_fields2: dont interpret max_b_frames of <0 as there being b frames. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Stefano Sabatini	25f139e72f	lavf/utils: fix typo in has_codec_parameters Replace "unspecified sample size" with "unspecified frame size". +10l.	13 years ago
Michael Niedermayer	a7fbc7d7b7	lavf: factor codec id forcing out Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Stefano Sabatini	29e972f67c	lavu/parseutils: add av_small_strptime() Make internal small_strptime() function public, and use it in place of strptime(). This allows to avoid a dependency on strptime() on systems which do not support it. In particular, fix trac ticket #992.	13 years ago
Clément Bœsch	5620088494	lavf: fix a few typo in some comments.	13 years ago
Clément Bœsch	9d9f34a3c1	lavf: remove a few useless AV_NOWARN_DEPRECATED(). read_seek was undeprecated in `e5c708151`.	13 years ago
Michael Niedermayer	19d8954966	find_stream_info: update last_dts more often This improves dts validity checks and consequently fps detection of files with invalid dts Fixes Ticket1681 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	12b1512e85	lavf/utils: Try to unwrap pts/dts so as to minimize wraps Based on code by: Andrey Utkin <andrey.krieger.utkin@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	254917f078	lavf/utils: run update_initial_timestamps() outside some if() This way it gets executed earlier and updated timestamps become available earlier. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Clément Bœsch	26ec392a0e	lavf: remove unused AVStream pointer.	13 years ago
Clément Bœsch	3dba9e19c8	lavf: add const qualifier to AVCodecDescriptor pointer in is_intra_only(). Fix "assignment discards ‘const’ qualifier from pointer target type" warnings.	13 years ago

Andrey Utkin	aec9390a9d	Check for avio fail in avformat_write_header, av_write_frame With minor changes by michael Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	b1511e00f6	lavf: probe PGS subtitles definition. The resolution is in the packets, so decoding must happen. Since most other formats do not set the dimension, make it a special case for PGS. If other codecs were to have the same requirement, using a CODEC_CAP would be preferred.	13 years ago
Michael Niedermayer	d5c90ff23b	lavf: reimplement is_intra_only() by using the AVCodecContext codec descriptor This also changes behavior as the descriptor table is more complete than the switch/case it replaces. As well as considering all non video as intra only Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Martin Storsjö	bdefe22b8e	lavf: Detect discontinuities in timestamps for framerate/analyzeduration calculation If the dts difference is more than 1000 times the average dts difference, restart the analysis. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	30c26c2442	lavf: Initialize the stream info timestamps in avformat_new_stream These are normally initialized to AV_NOPTS_VALUE at the start of avformat_find_stream_info, but if a new stream is found while this function is running (e.g. like in mpegts), the newly added AVStreams didn't have these values properly initalized, leading to avformat_find_stream_info terminating too soon (when the first timestamps are far from 0). Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Michael Niedermayer	a036ac5782	lavf: do not discard correct dts in favor of wrong pts for vc1-wmapro.ism Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Mans Rullgard	987170cb9d	dict: add av_dict_count() This adds a function to retrieve the number of entries in a dictionary and updates the places directly accessing what should be an opaque struct to use this new function instead. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Michael Niedermayer	b615dbb319	lavf: block special characters in dump metadata This is limited to the chars that arent filtered by av_log() already we might filter more aggressively if theres some case where this becomes needed.
