[FFmpeg-devel] [PATCH 1/6] lavu/hwcontext_qsv: specify Shift for each format

From: Haihao Xiang We can't get Shift from bit depth for some formats in the SDK. For example, bit depth is 10, however Shift is 0 for Y410 (XV30 in FFmpeg). In order to support these formats in the next commits, this patch specified Shift for each format Signed-off-by: Haihao Xiang --- libavu

[FFmpeg-devel] [PATCH 3/6] lavu/hwcontext_qsv: add support for 10bit 4:4:4 content on Linux

From: Haihao Xiang XV30 is used for 10bit 4:4:4 content in FFmpeg VAAPI, so XV30 should be used for 10bit 4:4:4 content in FFmpeg QSV too because QSV is based on VAAPI on Linux. However the SDK only declares support for Y410 but does nothing with the alpha in Y410, so this commit fudged a mapping

[FFmpeg-devel] [PATCH V2] lavc/libvpx: increase thread limit to 64

This change improves the performance and multicore scalability of the vp9 codec for streaming single-pass encoded videos by taking advantage of up to 64 cores in the system. The current thread limit for ffmpeg codecs is 16 (MAX_AUTO_THREADS in pthread_internal.h) due to a limitation in H.264 codec

Re: [FFmpeg-devel] [PATCH V2] lavc/libvpx: increase thread limit to 64

Removed unnecessary comment as requested by Ronald S. Bultje. some more thoughts about the patch: This is my deduction from what I could find - There was a hard limit of 16 threads in libvpx as there was no benefit to adding more threads based upon the parallelism available in the the codec. Thi
