* avutil/hwcontext_dxva2: Don't improperly free IDirect3DSurface9 objectsAaron Levinson2017-05-161-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | Add dxva2_pool_release_dummy() and use it in call to av_buffer_create() in dxva2_pool_alloc(). Prior to this change, av_buffer_create() was called with NULL for the third argument, which indicates that av_buffer_default_free() should be used to free the buffer's data. Eventually, it gets to buffer_pool_free() and calls buf->free() on a surface object (which is av_buffer_default_free()). This can result in a crash when the debug version of the C-runtime is used on Windows. While it doesn't appear to result in a crash when the release version of the C-runtime is used on Windows, it likely results in memory corruption, since av_free() is being called on memory that was allocated using IDirectXVideoAccelerationService::CreateSurface().

| * hwcontext_vaapi: Return all formats for constraints without configMark Thompson2016-06-211-111/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | No longer make a dummy device configuration to query. Instead, just return everything we recognise from the whole format list. Also change the device setup code to query that list only, rather than intersecting it with the constraint output. This makes hwupload more usable on mesa/gallium where the video processor only declares support for RGB formats, making it unable to deal with YUV formats before this patch. It might introduce some different trickier failures in the internal upload/download code because the set of allowed formats there has changed, though I didn't find any obvious regressions with i965.

|\| | | | | | | | | | | | | * commit '32c8359093d1ff4f45ed19518b449b3ac3769d27': lavc: export the timestamps when decoding in AVFrame.pts Merged-by: Hendrik Leppkes <h.leppkes@gmail.com>
| * lavc: export the timestamps when decoding in AVFrame.ptsAnton Khirnov2016-06-213-0/+11
| | | | | | | | | | | | | | | | | | | | | | Currently it's exported as AVFrame.pkt_pts, which is also the only use for that field. The reason it is done like this is that lavc used to export various codec-specific "timing" information in AVFrame.pts, which is not done anymore. Since it is confusing to the callers to have a separate field which is used only for decoder timestamps and nothing else, deprecate pkt_pts and use just AVFrame.pts everywhere.
