This is most certainly a bug in the i965-va-driver when disabling the non-free parts. Does evertyhing work as expected if you replace i965-va-driver with i965-va-driver-shaders (from non-free)? > [h264 @ 0x55b57872fd00] Failed to transfer data to output frame: -5. > Error while processing the decoded data for stream #0:0 > [aac @ 0x55b57872e4c0] Qavg: 1227.311 > [aac @ 0x55b57872e4c0] 2 frames left in the queue on closing > Conversion failed! > > For the second one: > $ ffmpeg -hwaccel vaapi -hwaccel_output_format vaapi -i cut.mp4 -c:v > h264_vaapi output.mp4 > ... > Stream mapping: > Stream #0:0 -> #0:0 (h264 (native) -> h264 (h264_vaapi)) > Stream #0:1 -> #0:1 (aac (native) -> aac (native)) > Press [q] to stop, [?] for help > ffmpeg: i965_encoder.c:1692: intel_enc_hw_context_init: Assertion > `encoder_context->mfc_context' failed.
