Jan Gerber	fc27e7272e	mpegts: do not export empty language tags Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Alexander V. Lukyanov	5adcef9c1b	mpegts: pass MpegTSContext ptr explicitly AVFormatContext->priv_data is not always a MpegTSContext, it can be RTSPState when decoding a RTP stream. So it is necessary to pass MpegTSContext pointer explicitly. Within libav, the write_section_data function doesn't actually use the MpegTSContext at all, so this doesn't change anything at the moment (no memory was corrupted before), but it reduces the risk of anybody trying to touch the MpegTSContext via AVFormatContext->priv_data in the future.

Vittorio Giovara	5397386eff	mathops: move macro to the only place it is used This helps in disentangling lavf and lavc too.	11 years ago
Leandro Dorileo	8370a6fa59	libavformat/mpegts: expose raw packet size We cannot easily determine if an mpeg TS's packet size is DVHS, FEC or so on, for that we need to expose the internal raw_packet_size field. Signed-off-by: Anton Khirnov <anton@khirnov.net>	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>	12 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.

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>	12 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>	12 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

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.

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
