* vdpau: add helper for surface chroma type and sizeRémi Denis-Courmont2014-12-25
| | | | | | | | | | | | | | | | | | | | | Since the VDPAU pixel format does not distinguish between different VDPAU video surface chroma types, we need another way to pass this data to the application. Originally VDPAU in libavcodec only supported decoding to 8-bits YUV with 4:2:0 chroma sampling. Correspondingly, applications assumed that libavcodec expected VDP_CHROMA_TYPE_420 video surfaces for output. However some of the new HEVC profiles proposed for addition to VDPAU would require different depth and/or sampling: http://lists.freedesktop.org/archives/vdpau/2014-July/000167.html ...as would lossless AVC profiles: http://lists.freedesktop.org/archives/vdpau/2014-November/000241.html To preserve backward binary compatibility with existing applications, a new av_vdpau_bind_context() flag is introduced in a further change.

* libavcodec: add AV_HWACCEL_ALLOW_HIGH_DEPTH flagRémi Denis-Courmont2014-12-25
| | | | | | | | This can be used by the application to signal its ability to cope with video surface of types other than 8-bits YUV 4:2:0. Signed-off-by: Rémi Denis-Courmont <remi@remlab.net> Signed-off-by: Anton Khirnov <anton@khirnov.net>
* avcodec: add AVCodecContext.sw_pix_fmtRémi Denis-Courmont2014-12-25
| | | | | | | | This carries the pixel format that would be used if it were not for hardware acceleration. This is equal to AVCodecContext.pix_fmt if hardware acceleration is not in use. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* libavformat: Only use MoveFileExA when targeting the desktop API subsetMartin Storsjö2014-12-19
| | | | | | | | | | | | | | | | The MoveFileExA is available in the headers regardless which API subset is targeted, but it is missing in the Windows Phone link libraries. When targeting Windows Store apps, the function is available both in the headers and in the link libraries, and thus there is no indication for the build system that this function should be avoided - such an indication is only given by the Windows App Certification Kit, which forbids using the MoveFileExA function. Therefore check the WINAPI_FAMILY defines instead, to figure out which API subset is targeted. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpenc_mpegts: Call write_trailer for the mpegts muxer even if no output ↵Martin Storsjö2014-12-19
| | | | | | | | | | buffer exists Since the mpegts muxer now can handle being called with a NULL AVIOContext, we don't need to try to allocate one before calling write_trailer. Signed-off-by: Martin Storsjö <martin@martin.st>
* mpegts: Support running the write_trailer function without an AVIOContextMartin Storsjö2014-12-19
| | | | | | | | If opening and closing dynamic buffers as AVIOContext, we may not have any AVIOContext available when wanting to close and deallocate the muxer. Allow calling write_trailer despite this. Signed-off-by: Martin Storsjö <martin@martin.st>

* libavformat: Add a muxer wrapping mpegts encoding into RTPMartin Storsjö2014-12-18
| | | | | | | | | | | | | | | Since this structurally is quite different from normal RTP (multiple streams are muxed into one single mpegts stream, which is packetized into one single RTP session), it is kept as a separate muxer. Since this structurally also behaves differently than normal RTP, all of the other muxers that do chained RTP muxing (rtsp, sap, mp4) would need to be updated similarly to handle this - in particular, creating one single rtp_mpegts muxer for the whole presentation instead of one rtp muxer per stream. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtp: Initial H.261 supportThomas Volkert2014-12-18
| | | | | | | | | | | | | | The packetizer only supports splitting at GOB headers - if such aren't available frequently enough, it splits at any random byte offset (not at a macroblock boundary either, which would be allowed by the spec) and sends a payload header pretend that it starts with a GOB header. As long as a receiver doesn't try to handle such cases cleverly but just drops broken frames, this shouldn't matter too much in practice. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpenc: Avoid brittle switch fallthroughsMartin Storsjö2014-12-18
| | | | | | | | | Instead explicitly jump to the default case in the cases where it is wanted, and avoid fallthrough between different codecs, which could easily introduce bugs if people editing the code aren't careful. Signed-off-by: Martin Storsjö <martin@martin.st>
* h261dec: Fix context initialization sequenceMichael Niedermayer2014-12-18
| | | | | | | | | | ff_mpv_common_init sets s->context_initialized. This fixes decoding of h261 in the cases where the demuxer hasn't already set the frame size. CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* h261enc: Disallow sliced encodingMartin Storsjö2014-12-18
| | | | | | | | | | | This avoids trying to do sliced encoding, even if a slice/packet size is requested (via the -ps option or the rtp_payload_size field), since the encoder currently doesn't support it (or at least our decoder can't decode it, even if the h261_encode_gob_header function is hooked up to be called from the slicing part in mpegvideo_enc.c).

* rtpdec_h263_rfc2190: Clear the stored bits if discarding buffered dataMartin Storsjö2014-12-18

* rtpenc: Set the AVFMT_TS_NONSTRICT flagMartin Storsjö2014-12-18
| | | | | | | | In particular, when packetizing mpegts into rtp, the input packet timestamp may come from more than one stream, which could cause multiple packets be written with the same timestamp. Signed-off-by: Martin Storsjö <martin@martin.st>
