Martin Storsjö	0f310a6f33	rmdec: Validate the fps value Abort if it is invalid if strict error checking has been requested. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago

Diego Biurrun	7950e519bb	Disable deprecation warnings for cases where a replacement is available	12 years ago
Michael Niedermayer	d35b6cd377	rmdec: Use the AVIOContext given as parameter in rm_read_metadata() This fixes crashes when playing back certain RealRTSP streams. When invoked from the RTP depacketizer, the full realmedia demuxer isn't invoked, but only certain functions from it, where a separate AVIOContext is passed in as parameter (for the buffer containing the data to parse). The functions called from within those entry points should only be using that parameter, not s->pb. In the depacketizer case, s is the RTSP context, where ->pb is null.

Anton Khirnov	85a5bc054c	lavf: remove disabled FF_API_R_FRAME_RATE cruft	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

Diego Biurrun	6774247a9d	avformat: Drop pointless "format" from container long names	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
Justin Ruggles	b0e9edc44f	avcodec: add a cook parser to get subpacket duration Fixes jittery video playback of rm files with cook audio.	13 years ago

Alex Converse	1697c29d75	rmdec: Honor .RMF tag size rather than assuming 18.	13 years ago
Diego Biurrun	75c553eb26	rmdec: adjust printf format string specifier to fix warning libavformat/rmdec.c:383: warning: format ‘%d’ expects type ‘int’, but argument 7 has type ‘int64_t’	13 years ago
Ronald S. Bultje	aac07a7a4c	rm: prevent infinite loops for index parsing. Specifically, prevent jumping back in the file for the next index, since this can lead to infinite loops where we jump between indexes referring to each other, and don't read indexes that don't fit in the file. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	e30b3e59a4	rmdec: when using INT4 deinterleaving, error out if sub_packet_h <= 1. We read sub_packet_h / 2 packets per line of data (during deinterleaving), which equals zero if sub_packet_h <= 1, thus causing us to not read any data, leading to an infinite loop.

Anton Khirnov	6e9651d106	lavf: remove AVFormatParameters from AVFormatContext.read_header signature	13 years ago
Diego Biurrun	3dc99a18d4	cosmetics: drop some pointless parentheses	13 years ago
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	d3e3ffa501	rmdec: don't set codec timebase. It's not supposed to be set outside of lavc. Set r_frame_rate instead.	13 years ago
Martin Storsjö	0882689116	rdt: Set AVFMT_NOFILE on ff_rdt_demuxer This makes rdt work again, which has been broken since `603b8bc2a1`. This commit made opening a demuxer without a file (or in this case, with a filename which can't be opened) fail, unless the demuxer actually declared AVFMT_NOFILE.

Anton Khirnov	3b3bbdd3e6	lavf,lavd: replace av_new_stream->avformat_new_stream part I. Trivial replacements with sed are done in this commit: sed 's/av_new_stream(\([^)]*\), 0)/avformat_new_stream(\1, NULL)/'	13 years ago

Laurent Aimar	3e033da847	rmdec: use the deinterleaving mode and not the codec when creating audio packets. It prevents crashes due to non initialized fields. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Kostya Shishkov	10397215aa	Use deinterleavers for demangling audio packets in RealMedia. Unlike other containers RealMedia stores its audio packets in scrambled form, with interleaver ID preceeding audio codec ID. Currently deinterleaving decision is tied to the codec while it's possible to have non-default deinterleaver with audio codec (like Int0 deinterleaver instead of specific one for Sipro).

Kostya Shishkov	7c1f6df4b5	rmdec: correct DTS calculation in RealMedia container. First, container stores only DTS and not PTS as it was believed.

Diego Elio Pettenò	c6610a216e	Prefix all _demuxer, _muxer, _protocol from libavformat and libavdevice. This also lists the objects from those two libraries as internal (by adding the ff_ prefix) so that they can then be hidden via linker scripts.	14 years ago
