Anton Khirnov	c3f9ebf743	lavf: make av_set_pts_info private. It's supposed to be called only from (de)muxers.	13 years ago
Anton Khirnov	2092232581	lavf: estimate frame duration from r_frame_rate. If r_frame_rate is set, it should be more reliable for this than either codec or stream timebase.	13 years ago
Janne Grunau	0945eddec0	pthread: do not touch has_b_frames Adding the thread count in frame level multithreading to has_b_frames as an additional delay causes more problems than it solves. For example inconsistent behaviour during timestamp calculation in libavformat. Thread count and frame level multithreading are both set by the user. If the additional delay caused by frame level multithreading needs to be considered in the calling code it has all information to take it into account. Should it become necessary to calculate a maximum delay inside libavcodec it should be exported as its own field and not reusing an existing field. Based on a patch by Michael Niedermayer.

Martin Storsjö	18579f08e7	avformat: Accept the ISO8601 separate format as input, too This makes the function accept the format of creation_time as output by demuxers (e.g. the mov demuxer), making the creation timestamp stay intact if transcoding. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	4a83541650	avformat: Interpret times in ff_iso8601_to_unix_time as UTC This function is used in muxers for parsing the 'creation_time' metadata key, for converting it to a time value. This makes it match the behaviour of the exported 'creation_time' metadata from demuxers, where it is in UTC, too. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Mans Rullgard	52767d891c	lavf: fix multiplication overflow in avformat_find_stream_info() Converting to double before the multiplication rather than after avoids an integer overflow in some cases. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Anton Khirnov	32caa7b13c	lavf: pass options from AVFormatContext to avio.	13 years ago
Martin Storsjö	9d77a8faf9	avformat: Use avio_open2, pass the AVFormatContext interrupt_callback onwards Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Martin Storsjö	9957cdbfd5	avformat: Use ff_check_interrupt	13 years ago
Andrey Utkin	055a141e44	lavf: don't leak corrupted packets Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Martin Storsjö	1c8c41ff07	avformat: Avoid a warning about mixed declarations and code Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	ce145690b6	avformat: Warn about using network functions without calling avformat_network_init This is to make developers aware of the fact that they will start using the new init function at some point. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Anton Khirnov	eb0de71058	lavf: don't return from void av_update_cur_dts()	13 years ago
Reimar Döffinger	bb3244dee2	Replace all usage of strcasecmp/strncasecmp All current usages of it are incompatible with localization. For example strcasecmp("i", "I") != 0 is possible, but would break many of the places where it is used. Instead use our own implementations that always treat the data as ASCII. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	b6d08f40aa	avformat: Add functions for doing global network initialization Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Ronald S. Bultje	38a4be3fa7	lavf: use number of output pictures for delay checks. This fixes false positives of has_codec_delay_been_guessed() for streams where not every input picture generates an output picture, such as interlaced H264.	13 years ago
Alex Converse	61856d06eb	probe: Restore identification of files with very large id3 tags and no extension. Restore behavior of identifying files with huge id3 tags as mp3 at AVPROBE_SCORE_MAX/4. This was broken in r25378 and subsequently removed in r25929.	13 years ago
Alex Converse	7a773d4d59	probe: Remove id3 tag presence as a criteria to do file extension checking. This only encourages our users to put id3v2 tags on non-mp3 files to opt into extension based probing.	13 years ago
Anton Khirnov	a2faa95151	lavf: make some seeking functions private Specifically av_update_cur_dts(), av_seek_frame_binary() and av_gen_search(). They are not supposed to be called outside lavf.	13 years ago
Anton Khirnov	a75034300f	lavf: simplify by using FFMAX/FFMIN.	13 years ago
Anton Khirnov	0842d58998	lavc: use avpriv_ prefix for ff_toupper4. It's used in lavf.	13 years ago
Anton Khirnov	1fa395e471	lavf: use avpriv_ prefix for ff_new_chapter(). It's used in libavdevice.	13 years ago
Justin Ruggles	9ef6c7977f	avformat: do not require frame_size for Speex. Having it there forces decoding of a frame in order to get frame_size, but it is not really needed for proper demuxing or decoding.	13 years ago
Anton Khirnov	569129a6dc	lavf: add avformat_new_stream as a replacement for av_new_stream. It takes a codec parameter, thus enabling codec-specific defaults.	13 years ago
Anton Khirnov	c10731e78b	lavf: deprecate AVFormatContext.file_size It's too unreliable to be useful. avio_size() should be called instead.	13 years ago
Justin Ruggles	b631fba936	avformat: add AVInputFormat flag AVFMT_NO_BYTE_SEEK. This will prevent seeking by bytes for formats that cannot handle this.	13 years ago
Justin Ruggles	0041cdba98	avformat: don't unconditionally call ff_read_frame_flush() when trying to seek. This prevents flushing the packet buffer when the input format does not support seeking.	13 years ago
Mans Rullgard	a31e9f68a4	lavf: fix signed overflow in avformat_find_stream_info() On the first iteration through this code, last_dts is always INT64_MIN (AV_NOPTS_VALUE) and the subtraction overflows in an invalid manner. Although the result is only used if the input values are valid, performing the subtraction is still not allowed in a strict environment. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Martin Storsjö	e81e5e8ad2	lavf: Avoid using av_malloc(0) in av_dump_format On OS X, av_malloc(0) returns pointers that cause crashes when freed. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Nicolas George	4ca59d1948	oggdec: add support for Xiph's CELT codec This patch also introduces CODEC_ID_CELT. Signed-off-by: Nicolas George <nicolas.george@normalesup.org> Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Mans Rullgard	bb416bd68c	lavf: do not set codec_tag for rawvideo If the demuxer did not set a codec_tag, there is none and inventing one makes no sense. This change stops the rawvideo "decoder" over-writing user-supplied pixfmt with one derived from the codec_tag. The pixfmt-codec_tag-pixfmt round-trip is lossy since several pixfmts map to the same codec_tag. This fixes fate-lavf-pixfmt with avfilter disabled.

Alex Converse	5ef953e84f	probe: Fix insane flow control. A loop control variable was shadowed inside the loop and never updated.	14 years ago
Stefano Sabatini	25dfda7f31	lavf: rename enc variable in utils.c:has_codec_parameters() Rename it to "avctx", the old name was confusing as the function is used also with decoder contexts. Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
