pixel 3a OTA 23 video recording. file not viewable

@messayisto what do you mean ? Can you shoot a video and play it without issues ? 1004 didn't change anything on my part - black start, then a bit of video
-
@emphrath I was on 1001, and that only worked on short videos. But after reading @messayisto post I updated to 1004 yesterday and I could shoot long videos and they would playback fine for me too. I have tried 720p and 1080p.
-
@arubislander ok, 1005 kinda did it for me. It's not fixed though. The video does play from the start but I guess it actually starts a couple of milliseconds late because sound does not match. It may look fine, until you start recording someone talking or you snap your fingers. It was not this way before, and VLC on waydroid shows the same playback issues. We're getting there though ^^ Could you guys check that video and sound match on your devices ?
-
@emphrath Indeed! I never record videos with my phone, so I didn't think to test this. But you are right audio is like up to 1 second behind the video on 1004 (I haven't updated yet today)
-
@arubislander same with me, sound is not simultaneously in 1005.
-
It's actually very unstable. The results seem to vary wildly from one test to another. For example, the behaviour we just described only holds for very short videos. I tried a long-ish video today (about a minute) and I don't even have an image, plus the duration is messed up again (shows an hour long video) and that's a regression there. Are you folks testing playback with a computer ? Because as much as media player definitely should be able to play the videos, presently the dev branch has hardware acceleration messed up - youtube plays very badly while it's smooth on stable.
-
@emphrath How long is long-ish?
I have tested with videos of 4+ mins. And I replay on the phone.
-
@arubislander OK, I made a 30 min long video (takes 30 mins to make one, lol). Just the sound plays, no video image. This is playing it back on the phone.
EDIT. I played all of the file. It looks like the audio and video is so much out of sync that the audio starts playing long before the video starts. About halfway through the reported length of the media file the video shows up. This seems to be an issue of the audio and video being severely out of sync.
-
I tested this as well as follows (record and play on the Pixel 3a phone):
OTA 23: Short videos seem to work fine, Longer >1 minute do not play correctly (mostly black screen)
Switched to devel (1005): "Long" video recorded previously does not play (did not expect that it does, but tested anyway), a new 1.5 minute long video was correctly played on the phone after recording (video + audio).I'm currently recording a longer one to see how this turns out
Edit: 50 minute long video is also fine. -
On dev 1007, things look much better ! Sound is still lagging behind, but the whole (30 secs) video plays. Good stuff
-
As of dev 1017, sound and video are completely off. Sound plays in the black for seconds before anything happens. Just doing the reporting here ^^
-
@emphrath It has been this way for me all along. I think it is the luck of the draw on rebooting.
-
GREAT NEWS EVERYONE !! As of dev 1022, sound and video are synchronized, and videos that are more than a minute long will actually play ! If you people can confirm this, I'll consider this topic solved !
-
@emphrath will let you know soon.
-
@emphrath Looks good to me
-
As of today dev-1026, a video over 2mn just doesn't play. So, topic not solved.
-
@emphrath I suspect that this the working / not working behavior has more to do with reboots than with specific updates.
-
@arubislander right.
-
Two things:
-
I found the reason for one particular A/V desync problem I could reproduce, and have proposed an MR: https://github.com/Halium/hybris-patches/pull/58
-
I'm tweaking the job to clean up old GStreamer caches earlier now, which hopefully results in proper recordability and playback ability after reboots.
