[FFmpeg-devel] [PATCH v3] libavcodec/vp8dec: fix the multi-thread HWAccel decode error

2019-06-11 Thread Shaofei Wang
Fix the issue: https://github.com/intel/media-driver/issues/317 the root cause is update_dimensions will be called multple times when decoder thread number is not only 1, but update_dimensions call get_pixel_format in each decode thread will trigger the hwaccel_uninit/hwaccel_init more than once.
