Bug ID: 455508
Summary: unable to import MKV or MP4 clips containing x.264
video with single stereo audio track. Files downgraded
to 'TS' using ffmpeg import OK.
Product: kdenlive
Version: 22.04.2
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: Video Display & Export
Assignee: j...@kdenlive.org
Reporter: rickstock...@reno-computerhelp.com
Target Milestone: ---
SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.
See
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***
Unable to attach a report via the KDE crash handler, it hangs on current
OpenSuse Tumbleweed updated today (with Kernel 5.18.2-1-default, melt and most
of KDE were updated among 5000+ other packages). New with this version and its
co-requisite MELT-7 and FFMPEG4, did not happen yesterday. KDE Apps are version
5.25.0, Frameworks is Tumblweed 5.94.0.
STEPS TO REPRODUCE
1. Create a project.
2. Add a valid and playable MP4 or MKV clip, containing one track of Stereo
audio using codec AAC (LAV), OPUS, or AC3.
OBSERVED RESULT
Instant crash results, with failing KDE crash handler.
EXPECTED RESULT
Successful Import to the Project.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: OpenSuse Tumbleweed, rev 06/06/14/2022 mlweed
(available in About System)
KDE Plasma Version: 5.25.0
KDE Frameworks Version: 5.90.4
Qt Version: 5.15.2+kde294-5.4
ADDITIONAL INFORMATION
Converted the Camera's "native" AC3 audio to Opus. AAC. and a re-encoded AC3
within both an MKV and MP4 container (with -moveflags present in the MP4
container conversion). No alternative audio version was succesfully imported. I
did not (yet) try importing the video track alone. Failing file size was about
20GB.
BYPASS:
A failing large file can be exported to a single long "ts" output file using an
external tool such as avidemux; the 'ts' version can then be imported to
kdenlive without issues.
