Martin Storsjö	fe208ca54b	rtpdec_hevc: Skip 1 byte (DOND) instead of 2 (DONL) between aggregation units Only the first aggregation unit has 2 bytes (DONL) prepended, if such a field is in use. Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago

Vittorio Giovara	f7cc6627c0	configure: Use pkg-config for libdc1394 discovery Since not all systems need the libraw1394 dependency, let pkg-config provide the list of libraries actually needed. The libdc1394-2.pc file has been included since version 2 (2008-01-05), so it should be safe to use.	10 years ago

Gilles Chanteperdrix	4438d1c6ed	rtsp: parse lang attribute in SDP Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
Gilles Chanteperdrix	1ec28a66f2	rtpdec: fix issue with conversion from unsigned to signed When receiving an RTCP packet, the difference between the last RTCP timestamp and the base timestamp may be negative. As these timestamps are of the uint32_t type, the result becomes a large integer. Cast the difference to int32_t to avoid this issue. The result of this issue is very large start times for RTSP streams, and difficulty to restart correctly after a pause.

Thomas Volkert	cbdd1806ea	rtpdec_hevc: Implement parsing of aggregated packets With significant changes by Martin Storsjö, to use the shared function instead of reimplementing it. Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
Martin Storsjö	b878ba03e7	rtpdec_hevc: Initialize variables to silence false positive compiler warnings For some reason, clang didn't warn about this prior to using the shared function. Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago

Clément Bœsch	a982c5d74f	tests: drop bc dependency We already have a dependency on awk and bc is sometimes not found in the base system. Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
Anton Khirnov	a06b0b1295	h264: initialize H264Context.avctx in init_thread_copy This prevents using a wrong (first thread's) AVCodecContext if decoding a frame in the first pass over all threads fails.	10 years ago
Anton Khirnov	0dea4c77cc	h264: only ref cur_pic in update_thread_context if it is initialized It may be empty if the previous thread's decode call did not contain a valid frame.	10 years ago

Peter Meerwald	76ce9bd8e2	libavutil: Add ARM av_clip_intp2_arm add ARM code for implementing av_clip_intp2 using the ssat instruction on Cortex-A8, av_clip_intp2_arm() is faster than av_clip_intp2_c() and the generic av_clip(), about -19% Signed-off-by: Peter Meerwald <pmeerw@pmeerw.net> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago
Peter Meerwald	bf07d813f6	libavutil: Add av_clip_intp2 there already is a function, av_clip_uintp2() that clips a signed integer to an unsigned power-of-two range, i.e. 0,2^p-1 this patch adds a function av_clip_intp2() that clips a signed integer to a signed power-of-two range, i.e. -(2^p),(2^p-1) the new function can be used as a special case for av_clip(), e.g. av_clip(x, -8192, 8191) can be rewritten as av_clip_intp2(x, 13) there are ARM instructions, usat and ssat resp., which map nicely to these functions (see next patch) Signed-off-by: Peter Meerwald <pmeerw@pmeerw.net> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago

Hendrik Leppkes	ff48ae94f9	hlsenc: remove the AVIOContext for the playlist from the muxer context Its only used in one function, having it in the context serves no purpose. Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago

Martin Storsjö	a335ed7671	rtpdec_h264: Remove an unnecessary check If src_len is too small for nal_size, we already print a warning above, and the next step is to check the while loop condition anyway, so this one serves no purpose. Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
Martin Storsjö	176903ce83	rtpdec_h264: Return immediately on errors in h264_handle_packet_stap_a Previously, errors were only logged but the code kept on trying, and never actually returning the error as a return value. Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago

Martin Storsjö	7650caf013	rtpdec_h264: Use av_realloc instead of av_malloc+mempcy This is similar to what was done for rtpdec_hevc in `ced7238cd0`. Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
Martin Storsjö	8bdbf49c6f	rtpdec_h264: Include the right header for AV_RB16 Including libavcodec/get_bits.h is superfluous for AV_RB16 - nothing in this file uses any actual bitstream reader. Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
Martin Storsjö	ba2e07909b	rtpdec_vp8: Set the keyframe flag This allows the output to be used with stream copy, which discards packet from the start until the first keyframe. Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
