Encoding of ISO-Files failed in latest nightly

Post by c.s.g. » Fri May 31, 2019 9:25 am

Description of problem or question:
I have 2 ISO-Files. In each file I want to encode 6 MKV-Files.
Encoding the six MKV-files of ISO-file one works as expected. But after encoding the first MKV-file of ISO-File two successfully handbrake is closing when trying to encode the second MKV-file of ISO-file two. After restart of handbrake 5 MKV-Files remain in the encoding queue. First file is marked with an !. Encoding then the remaining 5 MKV-files of ISO-file two works as expected.

In earlier versions of handbrake I did not have any problem encoding up to 6 ISO-files with over all up to 45 MKV-files.

Steps to reproduce the problem (If Applicable):
see Description of problem or question:

HandBrake version (e.g., 1.0.0):
Nightly 20190527163102-6c4e488-master (2019053001)

Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):
Microsoft Windows 10 Pro 1803 17134.799

With the offical release version 1.2.2 (2019022300) everything works as expected.

Maybe I found the "error" by myself.
On Tab "Video" there is a combobox "Video Codec".
The release version 1.2.2 runs without any problem with the selection "H.264 (x264)" in that combobox.
In the newset nightly I have to select "H.264 (AMD VCE)" in order to encode the two ISO-files without any problems.
At least it runs once without any problem with the new setting ;-).
So there must be a change in behaviour in the nightly which causes the error.

But ....
(1.) .... the new setting "H.264 (AMD VCE)" encodes twice as much frames per second (120 fps) as the old setting do (60fps).
(2,) .... the new generated MKV-files are about 50% bigger than the old ones.
(3.) .... time of encoding per MKV-file is halved.

If the quality of the new setting is as good as with the old setting i dont care.
But maybe someone could explain it to me anyway.

Just FYI, (1) and (3) mean the same thing ;) :P

For the failed x264 encodes, we need to see a log (the log you provided was taken just after the application started, you need to grab the log after you start the x264 encode) :)

I hope, I copied the right one. But I am afraid it is useless because the log is about the mkv-file "ISO_02_F1.mkv" but the problem mkv-file is "ISO_02_F2.mkv" and for that file there is no log in the activity folder. Starting encoding of "ISO_02_F2.mkv" at about 22:22.

A restart an simple retry creates "ISO_02_F2.mkv" at 03:22 this morning!?!?

And, as I said before, there are no problems with the offical 1.2.2 version of handbrake.

PS: the name of the log file is "activity_log2624.txt" not "ISO_01_F6.mkv 06-02-2019 22-06-04.txt" for example if the encoding was successful.
PPS: Maybe it is not a problem at the beginning of encoding of "ISO_02_F2.mkv" but at the end of "ISO_02_1.mkv", just a guess.
