pixel 3a OTA 23 video recording. file not viewable
-
Hello,
I've updated the 3a to OTA 23 recently.
I have problems recording video. The result is not viewable on multimedia reproducer, nor even on an ubuntu 20 desktop. Tried to watch it on vlc, totem... No way.
The properties show
Codec: H264 (constrained baseline profile.)
Frames per second N/A.
Lenght: 24 hours ( the video is about 2 minuts long).
No audio channels.
I just wonder if it just my phone or if it is a general bug.
Thanks in advance.

@uri I just switched from RC channel to Stable to test this out, and unfortunately I can confirm this is an issue.
Fortunately switching to RC fixes the issue for me.
-
I've just tried to verify the issue, but I can't reproduce it. Have you attempted one more reboot after the upgrade? I had to change the video de- and encoding backend to account for wireless display support.
-
Checked switching from RC to Stable again, and this time video playback continued to work.
@uri did you try rebooting the device again while still on stable as (at)fredldotme suggested?
-
SOLVED!!!!.
Just rebooted the phone.
Easy.... -
@uri Great. If it doesn't stay that way please let us know in a bug report, I can disable the offending piece of software permanently.

@fredldotme Topic actually not solved. Rebooting the Pixel did the trick for me, but now the bug is back and rebooting doesn't change a thing. Real issue there. I don't know which bug tracker I should submit this to, though... The mediaplayer git ?
-
@fredldotme Same on RC. I can still play the videos that were recorded before OTA-23. I'm so sad. I lost videos I was quite happy with.
-
@emphrath Will take care of it real quick.
-
@fredldotme Since you know what changes have been made, do you think the videos could be reverted to some readable format by converting them or sth, or are they just meaningless megabytes now ? Thanks for your work.
-
@emphrath If ffmpeg can handle them, then possibly. Other than that there is probably not much you can do. I know it sucks and probably hurts me the most (since I want to provide the features users care about) but yeah, don't know..
-
@emphrath Okay I have pushed a potential fix now, tomorrow's devel update should include it. In the meantime, try to copy your beloved videos to your PC, try to open them, and attempt to fix them with ffmpeg if possible.

@fredldotme No worries and thanks for the tip. I do know and love ffmpeg, but mostly command line. You're talking about a gui app, right ? And surely i'll try something but I would at least need to know what problems do I want to fix ^^
-
Btw for some reason vlc on android plays the sound of the video - which ut media can't do.
-
@fredldotme Hello there. The update on devel does give some video playback for videos that were recorded today - but only half of the video at best, and jagged color patterns may appear at the beginning or end.
-
@emphrath you mean during playback on the device itself? Have you tried watching them on a PC yet?
Also, I would suggest against UT Media app, it doesn't support hardware acceleration. -
@fredldotme I mentioned this morning that video playback works. And it did. Bit turns out this is only with short videos of under a minute. Now I made one of 3 minutes long and it doesn't play back either, I am sorry to report.
-
@fredldotme I don't have access to a PC and I won't before a long time. I ran ffmpeg through libertine and it did the job during my attempts to fix my old videos. For example, a mp4 to mp4 conversion yields a file the same size, but with the real duration attached, and a fix image. I run my playbacks with vlc on waydroid, which behaved the same way as media player for videos taken after your devel fix: black screen and sound at the beginning, and after a couple of seconds, the actual vidzo kicks in.
-
@fredldotme Same device, and on no channel video playback is possible. I changed channels several times and did several reboots. Now on devel with his mornings update same game
-
@messayisto The devel fix DOES work to some extent: you won't be able to read the videos you took after OTA23 but you should be able to play the ones you shot after moving to devel
