Re: Can I use QSV HW Accel from Linux GUI or command line ?

This thread spurred me to have another look at it. I got it working (both CLI and GUI) and have posted a PR for review https://github.com/HandBrake/HandBrake/pull/1922. You still have to build and install Intel's MediaSDK separately and you have to have all the proper libva*.so libraries installed f...

Re: NVidia NVENC encoder with Handbrake CLI

"Transcoding" (which is what HandBrake does) involves additional steps. Only the "encode" part may be getting done on the encoder ASIC that is sitting on the same die as your GPU. Transcoding involves decoding source video *and* audio, filter video (deinterlace, scale, etc), encode video and audio. ...

Re: Rip of 4K Blu-Ray gives No Valid Source or Title Found

4K blurays are partially supported in HandBrake's nightly build. I believe your disc will at least scan with the nightly build. More complete support in libbluray is on the way. It's actually waiting on me to do some reviews.

Re: Can I use QSV HW Accel from Linux GUI or command line ?

QSV on linux is a [Censored] show. It requires specific drivers with specific versions of various libraries that are not available from most linux distribution repositories. In addition, I can't run QSV on a single one of my machines. So as of now, HandBrake's QSV on linux is completely untested. No...

Re: 1.2 / 1.2.1 MUCH slower than 1.1.2 and previous

FYI, rebulding the contrib libraries like x265 requires a more thorough clean we call "xclean". To thoroughly clean everything

Code: Select all

make xclean
You can also clean individual contribs, e.g

Code: Select all

make x265.xclean

Try disabling the qsv decoder and use the software decoder instead. I believe the setting for this is in preferences.

Re: Foreign Audio Search ?

The point of FAS is you don't know which track has the subtitles for foreign audio scenes without doing some kind of search. To use your words, if there exists a specific track for foreign audio sections, which track is it? If FAS didn't exist, how would *you* determine which track to add to your en...

Re: Foreign Audio Search ?

First let me restate how foreign audio search works. If the "main language" matches your "preferred language" a list of all subtitle tracks that are in your preferred language is created. The subtitles in this list are scanned and the frequency of occurrence of subtitles is compared between the trac...

Your version of libgtk is too old. Version 3.22 or newer is required. You could probably safely comment out that call and it's associated error checking since there are backup methods of opening a web page employed in the event that call fails. Does xerus support flatpaks? If so, it may be easier fo...

Re: SRT files: extended ASCII characters (é è ï) removed?

First upgrade HandBrake . 0.10.5 is so old I can't even recall what sorts of bugs might have existed. Second post an activity log . If there were errors logged, it may give us more of a clue. But, you are most likely setting the wrong character code set for SRT input. Are you certain that your SRT f...

Re: Files are converted bigger

You only tried one of the things I suggested... and the file did get smaller than your last attempt. But as I also said (and s55 before me) you will have to lower the quality setting to achieve the size you are looking for.

What size are you hoping to achieve?

Re: Files are converted bigger

When transcoding video, the process works like this. The source is uncompressed to raw YUV format. YUV format is basically 12 bits per pixel. So in your case each frame is 1920 * 1080 * 12 bits ~= 3MB per frame. Your video is about 1hr 5min long and 30 frames per second which is about 117000 frames....

Re: Files are converted bigger

You might also want to try a slower video encoder preset (also on the video tab). The preset you've chosen is for fast encoding which sacrifices quality and size for speed.

Re: Files are converted bigger

Your source is already highly compressed, so you will have to sacrifice more quality. I expect you might be disappointed with the results of compressing it *more*. But if smaller is what you want, keep sliding the quality slider on the video tab to the left until you get the file size you are lookin...

Re: Set width and maintain aspect ratio for height

Your log doesn't show what you describe, so I'm a bit confused. The preset has height set to 720. Your log shows height is not 720 but 536 which seems to be the appropriate value.

Re: Set width and maintain aspect ratio for height

Can you also post your command line? If I had to guess, you are probably using --non-anamorphic option, but not using --keep-display-aspect. With your particular source, you don't need either of these since it is already non-anamorphic. But if you use the non-anamorphic option, you generally also wa...

Maybe a little more explanation will help. It's a common misconception that video encoding is easily massively parallelized.

Re: x.265 on Threadripper not using many cores

All the posts I've read show that it taxes the CPU more for the same source material Most of the benchmarks that are done try to either show how "good" the encoder is or try to be "fair" (i.e. do an apples to apples comparison). In either case, they would not pick a source and settings that would s...

Re: x.265 on Threadripper not using many cores

Although NUMA should help with certain encoding tasks using x265, I'm pretty sure this is not a factor in your particular case. I get about the same result as you on a non-NUMA processor. CPU utilization averages 60% for any particular core and encode fps averages about 9 for low resolution content ...
