panic while creating video from single frame
Hello,
on Debian bookworm (12.9.)
ntsc-rs/target/release/ntsc-rs-cli -i "FILE.jpg" -p "FILE.json" -o "FILE.mp4"
results in
ntsc-rs v0.9.2

Same true for the binary standalone for Linux.
So looks something is missing (no complains during compilation). Looks like it is related to gstreamer? All *.deb dependencies are installed.

thread caused non-unwinding panic. aborting.
btw.- it works if switched to ffv1 codec so it seems a missing x264 encoder (?). It does not depend on the source material (image, video).
Thanks!
UPDATE
it seems the problem is that ntsc-rs (cli + standalone) cannot work together with the gstreamer version from deb-multimedia.org. The gstreamer1.0-plugins-bad contains x265 but gstreamer1.0-plugins-ugly does not contain x264.
Suggestion
Please add to the installation instructions a warning to avoid installing gstreamer1.0 from the deb-multimedia.org repo.
Trying out Debian the "normal" Debian repo from debian.org and its mirrors -> it worked. On a different computer using gstreamer packages from deb-multimedia.org the cli + GUI crash and investigation shows x264 is missing in gstreamer. So there are two options:
- just install normal Debian and it should work (unless they remove x264 as well, have tested
bookworm, but nottrixieorsidyet)
which means avoid
-
gstreamerfrom deb-multimedia.org ie. doapt pinningforgstreameror do not use this repo at all
Will try to downgrade back to normal Debian and can leave a note here whether it worked.
For those who are unsure - to test on Debian (should work also for Ubuntu, Mint, etc.) for x264 encoder (using gstreamer)
Example x265 is present using deb-multimedia.org repo (gstreamer) and x264 is not present. On the terminal type
$ find /usr/lib/x86_64-linux-gnu/ -iname '*libgstx265*'
/usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstx265.so
whereas the following brings no response:
$ find /usr/lib/x86_64-linux-gnu/ -iname '*libgstx264.so*'
$
To get ntsc-rs output to h264 working it MUST give an output like for x265 above.
To find out which packages are installed type
dpkg -l *gstreamer*|grep ^ii
and to find out which repo was used for which package type e.g.
apt policy gstreamer1.0-plugins-ugly
