0001...patch is to fix the coredump issue. RefPicListx_count is less than the num_ref_listx because there's not enough reference pictures in dpb. After 0001 installed, the coredump is gone but last few frames displayed with mosaic blocks. The reason is gstreamer-vaapi doesn't process gaps_in_frame_num_value_allow_flag. 002...patch and 0003...patch is going to process 'non-exist' pictures and slide the reference window. gst-vaapi: qa branch 41940904625f7a3dbdf88d4d1f9fe2df4c434286 Issue can't be reproduced. close it. It can be reproduced again, both on PRC's tree and Gwenole's tree (In reply to comment #7) > It can be reproduced again, both on PRC's tree and Gwenole's tree MR3_TANDBERG_B.264 is a baseline profile. since baseline removed from gst-vaapi. so this file can't be tested now. I'll post a workaround to test baseline here. Created attachment 91403 [details] [review] h264-dec-workaround-to-enable-baseline-profile workaround to re-enable H.264 baseline profile to do more tests. At least this bug need enable baseline to test gaps in frame_num |
