Anton Khirnov	dbb1425811	lavf: make sure stream probe data gets freed. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	12 years ago
Anton Khirnov	aa3c779984	lavf: sanity check size in av_get/append_packet(). To avoid allocating ridiculous amounts of memory for corrupted files, read the input in chunks limited to filesize or an arbitrary large amount when that is not known (chosen to be 50M).	12 years ago

Anton Khirnov	1afddbe59e	avpacket: use AVBuffer to allow refcounting the packets. This will allow us to avoid copying the packets in many cases. This breaks ABI.	12 years ago
Reimar Döffinger	efa7f42020	Use the avstring.h locale-independent character type functions Make sure the behavior does not change with the locale. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Martin Storsjö	de9cd1b173	lavf: Handle the environment variable no_proxy more properly The handling of the environment variable no_proxy, present since one of the initial commits (`de6d9b6404`), is inconsistent with how many other applications and libraries interpret this variable. Its bare presence does not indicate that the use of proxies should be skipped, but it is some sort of pattern for hosts that does not need using a proxy (e.g. for a local network). As investigated by Rudolf Polzer, different libraries handle this in different ways, some supporting IP address masks, some supporting arbitrary globbing using *, some just checking that the pattern matches the end of the hostname without regard for whether it actually is the right domain or a domain that ends in the same string. This simple logic should be pretty similar to the logic used by lynx and curl. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Mans Rullgard	91ac403b13	lavf: fix arithmetic overflows in avformat_seek_file() The values compared here can be more than INT64_MAX apart. Since the difference is always positive, converting to uint64_t before subtracting gives the correct result without overflows. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Anton Khirnov	cb45553f57	Remove pointless #undefs of previously forbidden functions.	12 years ago
Justin Ruggles	261e9348ef	lavf: add a common function for selecting a pcm codec from parameters	12 years ago
Janne Grunau	7709ce029a	lavf: avoid integer overflow in ff_compute_frame_duration() Scaling the denominator instead of the numerator if it is too large loses precision. Fixes an assert caused by a negative frame duration in the fuzzed sample nasa-8s2.ts_s202310. CC: libav-stable@libav.org	12 years ago
Duncan Salerno	33893e6abc	url: Handle relative urls starting with two slashes This is defined by RFC 3986 section 5.4.1 to be handled this way. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Duncan Salerno	eea003814c	url: Handle relative urls being just a new query string Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Duncan Salerno	a6363e3d89	url: Don't treat slashes in query parameters as directory separators Strip off query parameters from the original url before applying the new relative path. Signed-off-by: Martin Storsjö <martin@martin.st>	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
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
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
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
Mans Rullgard	edb5238ccb	libavformat: add const to AVCodec pointers Signed-off-by: Mans Rullgard <mans@mansr.com>	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
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
Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	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
Anton Khirnov	aba232cfa9	lavf: deprecate r_frame_rate. According to its description, it is supposed to be the LCM of all the frame durations. The usability of such a thing is vanishingly small, especially since we cannot determine it with any amount of reliability. Therefore get rid of it after the next bump. Replace it with the average framerate where it makes sense. FATE results for the wtv and xmv demux tests change. In the wtv case this is caused by the file being corrupted (or possibly badly cut) and containing invalid timestamps. This results in lavf estimating the framerate wrong and making up wrong frame durations. In the xmv case the file contains pts jumps, so again the estimated framerate is far from anything sane and lavf again makes up different frame durations. In some other tests lavf starts making up frame durations from different frame.	13 years ago
Anton Khirnov	f66eeff1c8	lavf: round estimated average fps to a "standard" fps.	13 years ago
Anton Khirnov	fe1c1198e6	lavf: use dts difference instead of AVPacket.duration in find_stream_info() AVPacket.duration is mostly made up and thus completely useless, this is especially true for video streams. Therefore use dts difference for framerate estimation and the max_analyze_duration check. The asyncts test now needs -analyzeduration, because the default is 5 seconds and the audio stream in the sample appears at ~10 seconds.	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.
