I happily tried the new support for writing videos to the sd card with Sailfish 2.0.4.14 on my Jolla phone. Earlier, recording video to the internal storage resulted in a bricked (rescued via system image provided by kind fellow Jolla users) device as the btrfs manged to amalgate system files with the (corrupted) video file. So now, armed with a 32 GiB sd card formatted with ext4, I hoped to be finally ready to simply place my Jolla somewhere and record things without stupid arbitrary limits and without danger for the operating system.

It turns out that I still cannot just let the camera roll: I recorded for around 2.5 hours, got a 12 GiB file. Too bad that file fails to play after around 50 minutes in, also on a PC after copying. Ffmpeg says this:

Something is wrong in how the camera app stores the video. I've been told there is gstreamer used behind the scenes. Could this issue and patch be related?

Can someone confirm that this is what affects the Camera? Or is it an entirely different bug? So far I'm trying to figure out how to access the source rpm on my phone to check if the patch would apply.

The relevant versions of gstreamer are what should be normal for SFOS 2.0.4.14. especially gstreamer1.0-plugins-good-1.4.5+git9.1-1.6.1 .

you sure its ext4 and not fat32? :)

Gstreamer will be updated in Sailfish OS 2.0.5.6, which is now available for early access, so if you could test this again with the new version.

OK, I tested the early access SFOS update. It seems to indeed fix this!

I set a high bitrate (using kimmoli's camera settings plugin) of 16 Mbps (even higher values make the camera app choke on writing) and recorded 73 minutes into a file of 6.5 GiB size. It seems to be wholly playable in the gallery. But there is still one bug, hopefully without consequence: The details show a file size of -170242465.

I am astonished that there was a 32 bit integer used for indicating the size of video files. I hope this little bug does not have further consequences … but it would nevertheless be nice if it could be fixed before official release.

Once that issue is settled, I'd consider accepting an answer of "fixed in OS 2.0.5.6".

Can you check what

    tracker-info <path-to-the-big-file>

says about the fileSize?

Keto ( 2016-11-22 20:11:03 +0300 )edit

Well, first: tracker-info complains that it does not exist anymore and that I shall call it tracker info now.

Second: The size there looks OK, 6887510327. So it really is only a display issue in the video properties.

OK, I will answer the question myself, then: The immediate issue of not being able to record long videos over 4 GiB in size is resolved in SFOS 2.0.5.6. The minor issue of wrong filesize display in the gallery remains and I don't know why it would be of any difficulty patching that up, too, but I got another more important issue now.
