Hello,
It looks like a recent patch causes VA-API H.264 encode to stop working and an
assertion to be thrown. I ran a git bisect and narrowed it down to the
following commit:
32a618a948c20f18db102d0b0976790222a57105 is the first bad commit
commit 32a618a948c20f18db102d0b0976790222a57105

vaapi_h264: Do not use deprecated header type
SEI headers should be inserted as generic raw data (the old specific
type has been deprecated in libva2).
When run with the above patch, I get the following output:
[h264_vaapi @ 0x37d0a20] Warning: some packed headers are not supported (want
0xd, got 0xb).
[h264_vaapi @ 0x37d0a20] The encode compression level option is not supported
with this VAAPI version.
ffmpeg: i965_drv_video.c:352: va_enc_packed_type_to_idx: Assertion `0' failed.
Here’s the vainfo output which provides the version info for the driver, va-api
version, etc. This is on a Haswell system running Centos 7.
libva info: VA-API version 0.34.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib64/dri/i965_drv_video.so
libva info: Found init function __vaDriverInit_0_34
libva info: va_openDriver() returns 0
vainfo: VA-API version: 0.34 (libva 1.2.1)
vainfo: Driver version: Intel i965 driver - 1.2.2
I’m using the following command line for testing:
./ffmpeg -y -vaapi_device /dev/dri/card0 -i /home/devin/inputfile.ts -vf
'format=nv12,hwupload' -c:v h264_vaapi out.mp4
Any suggestions that could be offered would be greatly appreciated. Likewise
please let me know if there is any other information I can provide that would
assist in getting this resolved.
Thanks,
Devin Heitmueller
