[Bug]: DG2: Using `-extbrc 1` causes: Error initializing the encoder: invalid video parameters (-15)

JohnVillalovos commented 7 months ago

Which component impacted?

Encode

Is it regression? Good in old configuration?

None

What happened?

I have an Intel Arc A380 GPU and an i7-6700k (Skylake) (Intel HD Graphics 530).

A380 = renderD129
i7-6700k = renderD128

When I run the following command:

ffmpeg -hide_banner -init_hw_device vaapi=intel:/dev/dri/renderD129 -init_hw_device qsv=hw@intel -filter_hw_device hw \
 -an  -i input.mkv -frames:v 500 -c:v hevc_qsv -preset medium -profile:v main -async_depth 1 \
 -b:v 5000k -maxrate 10000k -bufsize 20000k -rc_init_occupancy 10000k -look_ahead_depth 40 \
 -extbrc 1 -b_strategy 1 -adaptive_i 1 -adaptive_b 1 -bf 7 -g 256 -strict -1 -fps_mode passthrough -y output.mkv

I get the error:

<snip>
[hevc_qsv @ 0x5646a02e8680] Error initializing the encoder: invalid video parameters (-15)
[vost#0:0/hevc_qsv @ 0x5646a02846c0] Error initializing output stream: Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

If I change the above command by changing renderD129 to renderD128 then it works.

ffmpeg -hide_banner -init_hw_device vaapi=intel:/dev/dri/renderD128 -init_hw_device qsv=hw@intel -filter_hw_device hw \
 -an  -i input.mkv -frames:v 500 -c:v hevc_qsv -preset medium -profile:v main -async_depth 1 \
 -b:v 5000k -maxrate 10000k -bufsize 20000k -rc_init_occupancy 10000k -look_ahead_depth 40 \
 -extbrc 1 -b_strategy 1 -adaptive_i 1 -adaptive_b 1 -bf 7 -g 256 -strict -1 -fps_mode passthrough -y output.mkv

If I use renderD129 and remove -extbrc 1 then it also works.

What's the usage scenario when you are seeing the problem?

Transcode for media delivery

What impacted?

No response

Debug Information

intel-media-driver-23.4.3-1.fc39.x86_64
Have both renderD128 and renderD129 in /dev/dri/

extbrc is majorly used for DG1 media delivery. May I know what's the reason you want to use it on DG2/ACM? Is it ok for you to remove it?

JohnVillalovos commented 7 months ago

I saw in https://github.com/intel/media-delivery/blob/c14a6d1e27a287e22b934e5c980282fa81d47d86/doc/quality.rst#L315-L337 that I should use it in order to use EncTools. And it seemed to recommend using EncTools. Is that not the case for DG2?
