I solved it. My problem was in LD_LIBRARY_PATH and missing libva.a. Now, all tests, are ok, but ffmpeg fails with segmentation fault.

Test command is conversion from hevc to h264.

ffmpeg -y -i ./test_out.h265.mp4 -c:v h264_qsv ffmpeg_out.qsv.mp4

comment:4 Changed 20 months ago by jkqxz

  • Resolution set to fixed
  • Status changed from new to closed

Working as of 1f26a231bb065276cd80ce02957c759f3197edfa.

(Note that the implementation currently defaults to the software encoder in the media SDK for compatibility reasons; add "-load_plugin hevc_hw" to use the hardware encoder.)
