Issue with Quick Sync Video (QSV) Hardware Acceleration in FFmpeg
6 mars 2024, par Linganiveth S.GIt appears that FFmpeg is unable to create the necessary QSV device for decoding the H.264 video stream.


I am writing to report an issue I encountered while attempting to use No device available for decoder error. hardware acceleration with FFmpeg on my system.


When I run the following command to test QSV hardware acceleration :


./ffmpeg -hwaccel qsv -i input.mp4 output.ts


I encounter the following error :


[AVHWDeviceContext @ 0x558c6886a5c0] Error setting child device handle: -17
Device creation failed: -1313558101.
No device available for decoder: device type qsv needed for codec h264_qsv.



It appears that FFmpeg is unable to create the necessary QSV device for decoding the H.264 video stream.


Here are some additional details about my system :


**- Operating System : Ubuntu 22.04.4 LTS


- 

- FFmpeg Version : 6.0
- Processor : 12th Gen Intel(R) Core(TM) i5-12400
- Graphics Card : Mesa Intel® UHD Graphics 730 (ADL-S GT1)**








I have ensured that my system meets the requirements for QSV hardware acceleration, but I am still encountering this issue.


Could anyone please assist me in resolving this issue ? Any guidance or suggestions provided would be greatly appreciated.

How to do the "TV Compression" thing in FFMPEG ?
7 août 2019, par ImagenyI’m trying to do this thing in FFmpeg where I make the picture a little better but I also compress the audio as heavily as on TV. I’ve tried everything, but nothing seems to be working out very well. I’m making this code for a VB program.
This is the result I want to achieve. It’s the first part of the video : https://streamable.com/3rjnp
That part was done using the audio effects in VEGAS Pro.
And this is the code I keep working on :
ffmpeg -i "inputfile.mp4" -s 1920x1080 -vf "minterpolate=59.94,tblend=all_mode=average,framestep=2, colorlevels=rimin=0.039:gimin=0.039:bimin=0.039:rimax=0.96:gimax=0.96:bimax=0.96, colorlevels=rimax=0.902:gimax=0.902:bimax=0.902, noise=alls=25:allf=t+u" -af "alimiter, dynaudnorm=p=1/sqrt(2):m=100:s=12:g=15, treble=f=1803:t=o:width=6:g=15, acompressor=threshold=0.3:ratio=20:attack=5:release=50, "volume=-12.7dB", dynaudnorm=m=100:r=1:s=15:g=3, aresample=48000, alimiter, acompressor=threshold=1:release=20, "volume=20dB", loudnorm, alimiter" -vcodec mpeg4 -acodec aac -ar 48000 -b:a 256k "outputfile.mp4"
How do I properly do it ?

FFMPEG reports different (wrong) video resolution compared to how it actually plays
30 mars 2015, par EmilianoQuick question, i have a movie, which was cut and rendered with Sony Vegas from its original format to a .wmv file. Here comes the tricky part, movie when played, either with
VLC
orWMP
, has a resolution of 656x480 ... BUT when i run a ffmpeg -i on it, it says it has a resolution of600x480
....I took the time of actually capturing a frame and croping it with photoshop and its
656
and not600
like ffmpeg its reporting, why would this could be happening ? How could i fix the headers resolution ? Would that have any impact on video re-rendering ? As i said, VLC and WMP seems not to care about the incorrect headers and are playing it right, BUT, jwplayer seems to be using the header information, which i don’t blame him, its correct to do that, but why the video headers could be wrong ?ffmpeg -i trailer.wmv
Input #0, asf, from ’trailer.wmv’ : Duration : 00:01:04.93, start : 3.000000, bitrate : 2144 kb/s Stream #0.0 : Audio : wmav2, 44100 Hz, mono, 32 kb/s Stream #0.1 : Video : wmv3, yuv420p, 600x480 [PAR 59:54 DAR 295:216], 2065 kb/ s, 25.00 tb(r)
And yeah, the
PAR/DAR
parameters are also wrong, but honestly, i don’t understand that technical shit, usually watch video and make sure it look good, any feedback would be appreciated :PIs there a way to change the container information with ffmpeg so applications that actually do use the container information don’t render video incorrectly ?
