Crash when changing video - V5.0.0 about pot HOT 18 CLOSED

Tested with V5.0.0_Beta1_PI1 and also V5.0.0_Beta1_PI2.... It happens in both versions

from pot.

Sorry, not able to reproduce this. Can you reproduce this with POCPlayer?

from pot.

I have just tested it with POCPlayer. It happens just with the POCPlayer included with the binaries of V5.0.0_Beta1_PI2 (But it seems to me like Beta1_PI1 includes an old version of POCPlayer because it lacks of some other problems I reported with V5.0.0)

As I reported, this problem happens with just some videos, but it seems to be a bug because it didn't happen early with same sources.

@carlonluca Have you tested with the video I shared?

from pot.

Yes, I tested that video. Not sure why, you can try beta2 and see if something has changed... but I couldn't reproduce so I did nothing specific.

from pot.

the crash always gives as final message

bool COMXVideo::PortSettingsChanged(): Assertion `data' failed.

Could it be that I lack of some library for some codec?...

from pot.

Video codec is h264, so it is provided by the pi. aac should be in ffmpeg, I provided it.
How much memory are you assigning to the GPU? Can you try beta2? Something changed that may influence that assert.

from pot.

This bug reproduces every time in my case. I've made the test for it. I don't use POCPlayer. So I see that only piomxtextures_pocplayer has changed in beta 2 since beta 1 (5.0.0 Pi2).

Here you can find the sources of my test.

Here you can find the video files for test (/video/adv1 and /video/adv2)

In testing first and second playback is normal. During third time there are missing frames with message "WARNING: One frame couldn't be shown.". At the begining of the fourth playback application crashes as it was described above in this comments.

I hope my information will help to fix it.

from pot.

@pavelliavonau I couldn't reproduce any issue with the files you sent me using your sources. Left playing for more than 10 loops. Can you test using beta2? Please check again the version you downloaded because I created a wrong package and there is now an updated version.

@Nightmare204 Can you provide some sample code to reproduce the issue. pocplayer here does not seem to be crashing but you're not the first one reporting this assertion.

from pot.

confirmed in Qt-rasp-5.5.0. It can change source only one time, the second time it gives a lot of these in the log (it doesnt stop):

05:02:30.693 WARNING: One frame couldn't be shown.

the third time (if i change source while it is displaying the above in the log after 10 seconds) it ends up with:

05:04:59.684 WARNING: No buffer available in any queue.
qmlscene: /home/luca/project/pi/pi/piomxtextures_src/omxplayer_lib/OMXVideo.cpp:401: bool COMXVideo::PortSettingsChanged(): Assertion `data' failed.
Aborted

I tested on PI2 with qmlscene and a simple qml that changes videos by rotation (without stopping them). I also tried to only stop video from a timer and then use:

onStopped: { // change source }
onStatusChanged: {
if (videoLoop.status == MediaPlayer.Loaded) {
// now new source is fully loaded
loopVideo.play()
}

but the result is the same

from pot.

on qt5.4.1 / PI2 i can not switch videos even once, it ends up with:

qml: switching to 1 /boot/public.eldorado/video/hit_gold.mp4

LOCKS HERE and stays liek this infinitely

here I do hot swaping, direct source change.

from pot.

the code

onStatusChanged: {
if (videoLoop.status == MediaPlayer.Loaded) {
// now new source is fully loaded
loopVideo.play()
}

is not needed, video starts playing automatically after new source is set, however it still crashes.

from pot.

tested the same QML on PI1 and the result is the same with both qt5.5.0 and qt5.4.1

from pot.

please let me know if you need my videos and QML.

from pot.

I already tried the pocplayer but I couldn't reproduce even with the provided video. Can you provide what is needed to reproduce?

from pot.

Luca, thank you very much for update. Beta 2 works fine in my case now. I'll give a feedback if I find new issues.

from pot.

piomxtextures_pocplayer in PiOmxTextures_5.0.0-beta1_pi1 / qt5.5 is affected by this bug. The behaviour is almost indetical to what i described only it lets me change 1 more videos before it crashes.

from pot.

beta2 fixes this. Great job!
