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.

Luca Barbato	bc54c2ae3c	libx264: add shortcut for the bluray compatibility option As for intra-refresh it is just a commodity.	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.

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.

Ben Avison	daf1e0d3de	avio: Add an internal function for reading without copying As long as there is enough contiguous data in the avio buffer, just return a pointer to it instead of copying it to the caller provided buffer. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Diego Biurrun	22a154e436	build: Add missing img2.o dependency to apetag.o	11 years ago
Diego Biurrun	bea3d6f436	ismindex: Replace mkdir ifdeffery by os_support.h #include os_support.h contains more precise workarounds for non-POSIX mkdir().	11 years ago
Rémi Denis-Courmont	f824535a4a	vdpau: deprecate bitstream buffers within the hardware context The bitstream buffers are now private and freed by libavcodec. For backward compatibility, the hold bitstream buffer pointer is left NULL (applications were supposed to av_freep() it). Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago

Anton Khirnov	488a0fa689	avconv: support -t as an input option. It limits the duration of the data read from a given input.	11 years ago
Anton Khirnov	811bd07846	avconv: make input -ss accurate when transcoding Insert (a)trim filters on the corresponding inputs, so the extra frames are decoded and discarded.	11 years ago
Anton Khirnov	56ee3f9de7	avconv: distinguish between -ss 0 and -ss not being used Using -ss 0 to drop frames with negative timestamps is a perfectly valid use case.	11 years ago
Anton Khirnov	2e661f26f8	avconv: insert extra filters in the same way for both graph inputs and outputs This will allow using the same code when one filter can be inserted both on input and output.	11 years ago

Luca Barbato	71953ebcf9	aac: Check init_get_bits return value Some code paths can call it with invalid length. CC: libav-stable@libav.org	11 years ago
Anton Khirnov	51fc88e746	avconv: improve some variable names 'filter' is too generic, since the functions in question deal with several filters. Also add const qualifiers to those variables.	11 years ago
Anton Khirnov	77cc958f60	lavfi: add const to the AVFilter parameter of avfilter_graph_create_filter() This function should never modify the filter.	11 years ago
Diego Biurrun	6da5b57da1	configure: Check for GCC diagnostic pragma support inside of functions The actual usage of the pragma is within functions and older versions of gcc only support the pragma outside of functions.	11 years ago

Vittorio Giovara	3c8bff0740	avframe: have av_frame_get_side_data take const AVFrame* Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago
Martin Storsjö	ee37d5811c	rtpproto: Allow specifying a separate rtcp port in ff_rtp_set_remote_url A separate rtcp port can already be set when opening the rtp protocol normally, but when doing port setup as in RTSP (where we first need to open the local ports and pass them to the peer, and only then receive the remote peer port numbers), we didn't check the same url parameter as in the normal open routine.

Martin Storsjö	1851e1d05d	rtpproto: Check the size before reading buf[1] I doubt that anyone ever would try to send a 1 byte packet via the RTP protocol, but check just in case - it shouldn't crash at least. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Vittorio Giovara	7748dd41be	avconv: add -n option to immediately exit when output files already exist Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	b85dbe68e2	avconv: Call exit_program instead of exit in avconv_opt as well This seems to have been missed in `636ced8e1d`. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	c7e921a54f	avopt: Check whether the object actually has got an AVClass AVIOContext has got an av_class member that only gets set if opening the context using avio_open2, but not if allocating a custom IO context. A caller that wants to read AVOptions from an AVIOContext (recursively using AV_OPT_SEARCH_CHILDREN) may not know if the AVIOContext actually has got a class set or not.
