Carl Eugen Hoyos	9fa75be96d	mpegts: add HEVC registration descriptor	11 years ago
Mickaël Raulet	b6a4701612	mpegts: Support HEVC demuxing Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Alexandra Khirnova	f369b9356c	avformat: Use av_reallocp_array() where suitable Signed-off-by: Diego Biurrun <diego@biurrun.de>	11 years ago
Ben Avison	5afe1d2791	avio: Add const qualifiers to ffio_read_indirect This provides at least some protection against potential accidental corruption of AVIO buffer workspace. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Ben Avison	a22ae9f0c5	mpegts: Remove one 64-bit integer modulus operation per packet The common case of the pointer having increased by one packet (which results in no change to the modulus) can be detected with a 64-bit subtraction, which is far cheaper than a division on many platforms. Before After Mean StdDev Mean StdDev Change Divisions 248.3 8.8 51.5 7.4 +381.7% Overall 2773.2 25.6 2372.5 43.1 +16.9% Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Ben Avison	c84ea750cf	mpegts: Make discard_pid() faster for single-program streams When a stream contains a single program, there's no point in doing a PID -> program lookup. Normally the one and only program isn't disabled, so no packets should be discarded. Before After Mean StdDev Mean StdDev Change discard_pid() 73.8 9.4 20.2 1.5 +264.8% Overall 2300.8 28.0 2253.1 20.6 +2.1% Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Ben Avison	cabb168169	mpegts: Remove one memcpy per packet This was being performed to ensure that a complete packet was held in contiguous memory, prior to parsing the packet. However, the source buffer is typically large enough that the packet was already contiguous, so it is beneficial to return the packet by reference in most cases. Before After Mean StdDev Mean StdDev Change memcpy 720.7 32.7 649.8 25.1 +10.9% Overall 2372.7 46.1 2291.7 21.8 +3.5% Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Can Wu	81cf53e133	mpegts: add support for stream_type 0x42, which is CAVS This allows demuxing and muxing of CAVS TS streams. Signed-off-by: Anton Khirnov <anton@khirnov.net>	12 years ago
Diego Biurrun	1ecdf8912b	avformat: av_log_ask_for_sample() ---> avpriv_request_sample()	12 years ago
Diego Biurrun	63d744e2be	av_log_missing_feature() ---> avpriv_report_missing_feature()	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
Martin Storsjö	a717f99042	mpegts: Share the cleanup code between the demuxer and lavf-internal parser functions The lavf-internal parser functions are used when receiving mpegts over RTP. This fixes memory leaks in this setup. The normal mpegts demuxer close function was updated in `ec7d0d2e` in 2004 to fix leaks, but the parsing function used for RTP wasn't updated and has been leaking ever since. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Michael Niedermayer	41540b36a1	bitstream: add get_bits64() to support reading more than 32 bits at once Also remove a duplicate function in the MPEG-TS demuxer. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	12 years ago
Diego Biurrun	15d35bee83	mpegts: Drop pointless casting of hex_dump_debug arguments	12 years ago
Diego Biurrun	72eaba5e4f	avformat: Convert some commented-out printf/av_log instances to av_dlog	12 years ago
Christian Schmidt	07584eaf4a	mpegts: check substreams before discarding Allow to extract the AC3 core from TrueHD with the "copy" codec. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Martin Storsjö	e6153f173a	avopt: Store defaults for AV_OPT_TYPE_INT in the i64 union member Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Ronald S. Bultje	ae2bb52cd2	mpegts: remove unused/incomplete/broken seeking code	13 years ago
Alex Converse	a8656cd425	mpegts: Remove disabled extension matching probe.	13 years ago
Joakim Plate	68b9ed8391	mpegts: Some additional HDMV types and reg descriptors for mpegts Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	13 years ago
Martin Storsjö	df8aa4598c	mpegts: Make sure we don't return uninitialized packets This fixes crashes, where the demuxer could return 0 even if the returned AVPacket isn't initialized at all. This could happen if running into EOF or running out of probesize with non-seekable sources. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	269cb6751b	mpegts: Try seeking back even for nonseekable protocols The mpegts demuxer reads 5 KB at startup just for discovering the packet size. Since the default avio buffer size is 32 KB, the seek back to the start will in most cases be within the avio buffer, and will in most cases succeed even if the actual protocol isn't seekable. This makes the demuxer startup faster/with less data when reading data from a non-seekable input, by not skipping the first few KB. If it fails, don't warn if the protocol isn't seekable, making it behave as before in the failure case. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	20234a4bd7	cosmetics: Align muxer/demuxer declarations Also add missing trailing commas, break long codec_tag lines and add spaces in codec_tag declarations. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Alex Converse	c9024a9fd7	mpegts: Fix dead error checks	13 years ago
Alex Converse	100c3fb2d1	mpegts: Always honor a registration descriptor if present and there is no other codec information.	13 years ago
Alex Converse	1aa708988a	mpegts: Pad the packet buffer in handle_packet(). This allows it to be used with get_bits without the thread of overreads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Alex Converse	4df369692e	mpegts: Do not call read_sl_header() when no bytes remain in the buffer. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Alex Converse	41bdd4adc4	mpegts: Suppress invalid timebase warnings on DMB streams. timestamp_len and timestamp_res intialize to zero.	13 years ago
Alex Converse	d9b89b23df	mpegts: Fix typo in handling sections in the PMT. This was an error rebasing `4682a1dc3a` for commit. The "pes" variable guaranteed to be NULL in that block.	13 years ago
Vladimir Pantelic	65a25adc97	mpegts: replace some magic numbers with the existing define Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Anton Khirnov	cd3716b9aa	Replace all uses of av_close_input_file() with avformat_close_input().	13 years ago

Diego Biurrun	da9cea77e3	Fix a bunch of common typos.	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	3110ad8329	mpegts: set stream id on just created stream, not an unrelated variable Bug introduced in `84ad31ff18`. Thanks to Uoti Urpala for finding it.	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	84ad31ff18	lavf: replace av_new_stream->avformat_new_stream part II. Manual replacements are done in this commit. In many cases, the id is some constant made up number (e.g. 0 for video and 1 for audio), which is then not used in the demuxer for anything. Those ids are removed.	13 years ago
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
Anton Khirnov	145f741e11	AVOptions: rename FF_OPT_TYPE_* => AV_OPT_TYPE_*	13 years ago
