RE: Hardware Transcoding doesn't work, AMD iGPU, Unraid - yannn - 2024-08-06

surprisingly it gives an error.
Tried to fix it but it didn't work. Should I change something?

Code:
[NULL @ 0x5583fa73b700] Unable to find a suitable output format for 'aac'

aac: Invalid argument

I tried to change it to

Code:
/usr/lib/jellyfin-ffmpeg/ffmpeg -hwaccel vaapi -hwaccel_output_format vaapi -vaapi_device /dev/dri/renderD128 -i "/data/movies/The.Acolyte.S01E03.Destiny.2160p.DSNP.WEB-DL.DDP5.1.HDR.H.265-NTb.mkv" -map_metadata -1 -map_chapters -1 -threads 0 -map 0:0 -map 0:1 -map -0:s -c:v h264_vaapi -b:v 3616002 -maxrate 3616002 -bufsize 7232004 -profile:v high -level 41 -force_key_frames 0 -c:a aac -ac 2 -b:a 384k -af "volume=2" -avoid_negative_ts disabled output.mkv

and it returned

Code:
[h264_vaapi @ 0x556b12d57840] No usable encoding profile found.

[vost#0:0/h264_vaapi @ 0x556b12d57540] Error initializing output stream: Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

[aac @ 0x556b12e154c0] Qavg: 64051.414

[aac @ 0x556b12e154c0] 2 frames left in the queue on closing

anything else I can check?

Many thanks for your help!

Try removing "-hwaccel vaapi". I'm wondering if your iGPU doesn't support decoding your video. Removing that parameter will move the decoding to the CPU, but the ENCODING will still happen on the iGPU.

Code:
/usr/lib/jellyfin-ffmpeg/ffmpeg -hwaccel_output_format vaapi -vaapi_device /dev/dri/renderD128 -i "/data/movies/The.Acolyte.S01E03.Destiny.2160p.DSNP.WEB-DL.DDP5.1.HDR.H.265-NTb.mkv" -map_metadata -1 -map_chapters -1 -threads 0 -map 0:0 -map 0:1 -map -0:s -c:v h264_vaapi -b:v 3616002 -maxrate 3616002 -bufsize 7232004 -profile:v high -level 41 -force_key_frames 0 -c:a aac -ac 2 -b:a 384k -af "volume=2" -avoid_negative_ts disabled output.mkv

RE: Hardware Transcoding doesn't work, AMD iGPU, Unraid - yannn - 2024-08-06

nope

Code:
Impossible to convert between the formats supported by the filter 'Parsed_null_0' and the filter 'auto_scale_0'

Error reinitializing filters!

Failed to inject frame into filter network: Function not implemented

Error while processing the decoded data for stream #0:0

so mine video is HEVC, my iGPU supports it. VNC 1.0 https://en.wikipedia.org/wiki/Video_Core_Next (Raven)
It supports decode + encode

Video stream: Stream #0:0: Video: hevc (Main 10), yuv420p10le(tv, bt2020nc/bt2020/smpte2084), 3840x2160 [SAR 1:1 DAR 16:9], 24 fps, 24 tbr, 1k tbn (default)

And we saw before with that legacy command as it was doing something on my iGPU

What I also found, that my TV supports HEVC hardware https://webostv.developer.lge.com/develop/specifications/video-audio-220
So maybe it's a reason why iGPU isn't used? But still I'm not sure why it loads 4 cores x 8 threads was 40-70%
That's a bit not clear for me...

Tried to play on TV and on my macbook again. Here are fresh logs: ffmpeg https://pastebin.com/w15Qe5gN , general https://pastebin.com/DCqPv17u

Did a few changes.
Passed the whole /dev/dri, changed transcording folder to the one at SSD, not at 5400 HDD.
CPU is lower. Stil a bit of sound, don't like it after macbook airs. Brobably need buy another mini pc or buy wifi 6 m2 card and move it to the closet

thank you for you time. Right now I think I'm done here
