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>	12 years ago
Michael Niedermayer	8470e6c96f	lavf/avformat_seek_file: fix harmless integer overflow Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	41dba453f9	utils/update_stream_timings: fix division by zero Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	b422e2c58a	compute_pkt_fields: fix harmless integer overflow Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	8a0118b4b4	ffio_read: dont spam the user at EOF with a truncation error Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Stefano Sabatini	25f139e72f	lavf/utils: fix typo in has_codec_parameters Replace "unspecified sample size" with "unspecified frame size". +10l.	12 years ago
Michael Niedermayer	a7fbc7d7b7	lavf: factor codec id forcing out Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 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.	12 years ago
Clément Bœsch	5620088494	lavf: fix a few typo in some comments.	12 years ago
Clément Bœsch	9d9f34a3c1	lavf: remove a few useless AV_NOWARN_DEPRECATED(). read_seek was undeprecated in `e5c708151`.	12 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
Michael Niedermayer	85a576775e	lavf: factor ff_free_stream() out Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 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
Mans Rullgard	edb5238ccb	libavformat: add const to AVCodec pointers Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Michael Niedermayer	11f8f2c0f3	avformat: export queue_attached_pictures Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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
Anton Khirnov	885da7b082	lavf: simplify is_intra_only() by using codec descriptors.	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. Fixes Ticket1181 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	13 years ago
Clément Bœsch	16dc5f2050	Replace various inlined inverse AVRational with av_inv_q().	13 years ago
Martin Storsjö	6c071a2b38	lavf: Declare an AVRational struct without a struct literal At this place, the normal way of initializing a struct works fine, there's no need for a struct literal. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Michael Niedermayer	3e1cf49676	compute_pkt_fields: do not attempt to calculate dts when the delay hasnt been estimated. Fixes ticket1242 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	2107009e7d	lavf: move nb_decoded_frames out of info. This way the variable is available outside find_stream_info Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	b288b4c63f	has_decode_delay_been_guessed: adjust value for has_b_frames=0 needed for a mkv file Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
