* avconv: only set SAR once on the decoded frame.Anton Khirnov2012-04-09
| | | | No point in repeating the assignment for each output stream.
* avcodec: validate the channel layout vs. channel count for decodersJustin Ruggles2012-04-08
| | | | | Set avctx->channel_layout to 0 if the channel count does not match avctx->channels.

* vaapi: mpeg2: fix slice_vertical_position calculation.Gwenole Beauchesne2012-04-08
| | | | | | | | | | | | | | | | | VASliceParameterBufferMPEG2.slice_vertical_position shall express the slice vertical position from the original bitstream. The HW decoder will correctly decode to the right line computed from the appropriate top_field_first and is_first_field flags. This patch aligns with DXVA's definition, which is what most HW and drivers expect. In particular, Intel PowerVR (Cedarview et al.) and NVIDIA (through VA-to-VDPAU layer). Since it looks more complex to fix binary drivers, I aligned the Intel Gen driver (Sandy Bridge et al.) to this behaviour, while maintaining compatibility with codec layers not providing this patch yet.

* hwaccel: mpeg2: decode first field, if requested.Gwenole Beauchesne2012-04-08
| | | | | | | | | | | | | | | | | | | If user opted to present fields as they come, then the first field picture needs to be submitted to the HW for decoding. In particular, this fixes MPEG-2 decoding of interlaced streams. Tested on Intel Cedar Trail, Sandy Bridge and Ivy Bridge platforms. Someone reported on the ffmpeg-devel@ list this also works on DXVA (Windows) and other Linux platforms (NVIDIA, through the VA wrapper). This also means a similar patch to non-hwaccel VDPAU may be necessary. Note: I believe the SLICE_FLAG_ALLOW_FIELD is useless since the first field shall always be submitted to the HW anyway. Nobody uses HW accels (dxva, vaapi, vdpau, etc.) without that flag though. Signed-off-by: Gwenole Beauchesne <gwenole.beauchesne@intel.com> Signed-off-by: Martin Storsjö <martin@martin.st>

* rtsp: Don't expose the MS-RTSP RTX data stream to the callerMartin Storsjö2012-04-08
| | | | | | | | This avoids exposing a dummy AVStream which won't get any data and which will make avformat_find_stream_info wait for info about this stream. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpdec_asf: Set the no_resync_search option for the chained asf demuxerMartin Storsjö2012-04-07
| | | | | | | | | | Searching for packet markers doesn't make sense for this use case, where packets are fed one at a time to the demuxer. This fixes playing back streams that have packets not starting with the 0x82, 0x00, 0x00 marker. Signed-off-by: Martin Storsjö <martin@martin.st>

* avconv: drop support for building without libavfilter.Anton Khirnov2012-04-06
| | | | | | | Since the mandatory memcpy in vsrc_buffer has been eliminated, there shouldn't be any significant reason to build without lavfi anymore. This will make upcoming support for complex filtergraphs easier to do.

* libavformat: Only require first packet to be known for audio/video streamsJoakim Plate2012-04-06
| | | | | | | | It can take a long time before subtitles or data streams show up, so we shouldn't wait for those before assuming we have all info for streams. Signed-off-by: Martin Storsjö <martin@martin.st>
* avplay: Don't try to scale timestamps if the tb isn't setMartin Storsjö2012-04-06
| | | | | | | | | | If get_filtered_video_frame failed above, tb might not be initialized at all, so don't scale using it. This fixes cases where avplay could crash if aborting avformat_find_stream_info with ctrl+c. Signed-off-by: Martin Storsjö <martin@martin.st>

* avfiltergraph: try to reduce format conversions in filters.Anton Khirnov2012-04-01
| | | | | | | | | | | | | Current code, with a filterchain such as (input - yuv411) -> (scale - any) -> (sink - any) will result in yuv420 being chosen for the second link, which is clearly not right. This commit attempts to improve in the following way: repeat until convergence: loop over all filters find input link with exactly one format force this format on all output links of the same type (if possible)
