GPU Acceleration

[aderlopas]

Is this something you expect to change?  If so perhaps you need to research  ffmpeg options to see if and or how to make it work with your card.  Here is some starting point for this.

Code:

"C:\Program Files\NPVR\Other\ffmpeg.exe" -y  -hwaccel:v:0 d3d11va -hwaccel_device:v:0 0 -i http://127.0.0.1:8866/live?channeloid=7562&transcoder=3f149498-ce76-492c-a394-c0b2ab103364&client=5c53419a-db74-43eb-b730-b60c7506a7e8 -map_metadata -1 -threads 0 -ignore_unknown -map 0:v:0? -map 0:a:0 -map -0:s -codec:v:0 h264_qsv -b:v 1500000 -maxrate 1500000 -bufsize 3000000 -codec:a:0 aac -strict experimental -ac 2 -ab 128000 -y NUL

Martin.

Thanks Martin for your response, as I am a bit ignorant of ffmpeg usage, where should I be adding this command in NextPVR?

[mvallevand]

Just open a command prompt and paste it to run it.

Many thanks Martin for the clarification. After many lines like the one below:

[h264 @ 064c58c0] SPS unavailable in decode_picture_timing

[h264 @ 064c58c0] no frame!

In the end I get the below:

You probably needed quotes around the http url in the middle of that command line.

You probably needed quotes around the http url in the middle of that command line.

Thanks Sub, so I added the quotes as follows:

"C:\Program Files\NPVR\Other\ffmpeg.exe" -y  -hwaccel:v:0 d3d11va -hwaccel_device:v:0 0 -i "http://127.0.0.1:8866/live?channeloid=7562&transcoder=3f149498-ce76-492c-a394-c0b2ab103364&client=5c53419a-db74-43eb-b730-b60c7506a7e8" -map_metadata -1 -threads 0 -ignore_unknown -map 0:v:0? -map 0:a:0 -map -0 -codec:v:0 h264_qsv -b:v 1500000 -maxrate 1500000 -bufsize 3000000 -codec:a:0 aac -strict experimental -ac 2 -ab 128000 -y NUL

And now I get the below:

[NULL @ 0761ba00] Unable to find a suitable output format for 'NUL'
NUL: Invalid argument

[sub]

Replace that "NUL" at the end with something like c:\temp\test.ts

[aderlopas]

OK, I figured out that instead of -y NUL, I must put: -f null NUL

So command becomes:

Code:

"C:\Program Files\NPVR\Other\ffmpeg.exe" -y  -hwaccel:v:0 d3d11va -hwaccel_device:v:0 0 -i "http://127.0.0.1:8866/live?channeloid=7562&transcoder=3f149498-ce76-492c-a394-c0b2ab103364&client=5c53419a-db74-43eb-b730-b60c7506a7e8" -map_metadata -1 -threads 0 -ignore_unknown -map 0:v:0? -map 0:a:0 -map -0:s -codec:v:0 h264_qsv -b:v 1500000 -maxrate 1500000 -bufsize 3000000 -codec:a:0 aac -strict experimental -ac 2 -ab 128000 -f null NUL 2>output.txt

So the output now is as in the file attached mainly with the below errors:

[h264 @ 07205f00] Failed to execute: 0x80070057
[h264 @ 07205f00] hardware accelerator failed to decode picture

and

[h264_qsv @ 07efeb00] Warning during encoding: incompatible video parameters (5)

[mvallevand]

Try

ffmpeg -encoders

and

ffmpeg -decoders

and see what you support for h264

If you have grep on your PC add | grep qsv to make that easier.

Found this issue with ffmpeg:

https://trac.ffmpeg.org/ticket/6418

I cannot tell if this is fixed in 4.2 or not...I saw that it was still an issue with 4.0 on Ubuntu....

Might be relevant?
