Anton Khirnov	af1761f7b5	ffmpeg: init filtergraphs only after we have a frame on each input This makes sure the actual stream parameters are used, which is important mainly for hardware decoding+filtering cases, which would previously require various weird workarounds to handle the fact that a fake software graph has to be constructed, but never used. This should also improve behaviour in rare cases where avformat_find_stream_info() does not provide accurate information. This merges Libav commit `a3a0230`. It was previously skipped. The code in flush_encoders() which sets up a "fake" format wasn't in Libav. I'm not sure if it's a good idea, but it tends to give behavior closer to the old one in certain corner cases. The vp8-size-change gives different result, because now the size of the first frame is used. libavformat reported the size of the largest frame for some reason. The exr tests now use the sample aspect ratio of the first frame. For some reason libavformat determines 0/1 as aspect ratio, while the decoder returns the correct one. The ffm and mxf tests change the field_order values. I'm assuming another libavformat/decoding mismatch. Signed-off-by: wm4 <nfxjfg@googlemail.com>	8 years ago
Zhengxu	1a79b8f8d2	ffmpeg: Add an option "qsv_device" to choose proper node for QSV child device (vaapi or dxva2) Reason: For some cases, such as 2 or more graphics cards existing, the default command line may fail because ffmpeg does not open the correct device node: ffmpeg -hwaccel qsv -c:v h264_qsv -i test.264 -c:v h264_qsv out.264 Let user choose the proper one by running like below: ffmpeg -hwaccel qsv -qsv_device /dev/dri/renderD128 -c:v h264_qsv \ -i test.264 -c:v h264_qsv out.264 Signed-off-by: ChaoX A Liu <chaox.a.liu@gmail.com> Signed-off-by: Huang, Zhengxu <zhengxu.maxwell@gmail.com> Signed-off-by: Andrew, Zhang <huazh407@gmail.com> Signed-off-by: Mark Thompson <sw@jkqxz.net>	8 years ago
Mark Thompson	03cef34aa6	ffmpeg_qsv: Fix hwaccel transcoding Set up the encoder with a hardware context which will match the one the decoder will use when it starts later. Includes `02c2761973`, with additional hackery to get around `a3a0230a98` being skipped.	8 years ago
Jun Zhao	46bfc1562f	ffmpeg/qsv: fix QSV-accelerated transcode performance drop issue. the merge commit `1b04ea1` "avconv: create simple filtergraphs earlier" will init the filtergraphs earlier, then init the QSV transcode can't suppose the nb_filters's value, else lead to the QSV transcode performance drop.
