Has video/media playback improved?
-
@chromiumos-guy sadly that wasn't my experience last year, it was very hit and miss, and notably .mkv files never worked. I don't know if it's a codec issue, but if it's down to Hallium it's probably still the same in 24.04. Just wanted to check before attempting to install once more.

Honestly, I don't know which handles which codecs UT supports. Is it in the Android stack or Linux/UT stack?
Recently, I encountered an mp4 file that's just black with sound during playback when played on a web based player. Local playback doesn't work at all. I edited a bit on Kdenlive and the resulting mp4 file played fine in UT. -

do you have a link to a .mkv file that was problematic for you ? I'm willing to try it on my phone if yes.

hmm, for lack of an answer, via matroska.org; I found 8 .mkv test files; 5 are playing fine on UT, 2 are failing because of a missing mpeg4 codec - I think that it is the same bug as this one in fact, the fix that is known in principle just needs to find a bit of storage space, and the test4.mkv has a broken structure - vlc can play it because it papers over the problem, but gstreamer on a standard Ubuntu workstation can't; it's a gstreamer limitation.
So Halium has very probably no relationship with problems reading .mkv files. That's entirely a linux level matter. -
Hello,
the native video player is not optimal. As a solution that actually always works I use mpv in liberline on the shell.
greetings

mpv can also be installed via snap.

@gpatel-fr it was about a year ago, I didn't do extensive testing, but none of the .mkv I tried worked, and .mp4 were very hit-and-miss. Good to know it isn't Hallium-related, perhaps there's hope to fix it on this device.
@Charly the issue w/ that is that, AFAIK, Libertine apps aren't hardware-accelerated, and video playback often gets choppy (it was one of the workarounds I tried). Didn't try the snap version though.
-
So noone who owns this device can provide any feedback on media playback? I'm planning to reinstall UT anyway, but would rather avoid running into this issue.

@hlbkv Hi, I have fresh tablet with UTouch (24.04). I've verified that:
mp4(checked 2 files),m4vandmkvplays without problems in default app. Howeverts2file don't work. -

a .mkv file is a container format, so the ability of UT mediaplayer to play these files depends on what is exactly the format of media tracks in the file. If the video track is "standard" mp4 or theora or h264 and sound track is mp3 or ogg/vorbis, there will be no problem. If for example the sound is amr or video is 'microsoft' mp4, it will probably not work.
It's not obvious to check on the format of a .mkv file under Ubuntu Touch, it's much easier under a PC running Linux where you can easily install mkvinfo (ffplay or gst-discoverer-1.0 will also be able to interpret the files to some extent).
