Crashes while viewing clip #1115
Comments

Updated to add formatting that I originally forgot to do, and make post clearer. Anyone having similar problems? |
|
I also have trouble with the "swscaler deprecated pixel format" issue, however, no crashes yet. It seems to relate to an long known ffmpeg issue, in sluggy dealing with mpeg pixel format. I'll keep you informed |
|
after some testing I think I can tell, regarding flowblade, it seems to be the other way round: I can check files with I can convert with without GPU acceleration this might look like Loading such converted videos into flowblade does not show any visual difference and renders without the Mabe it is a helpful workaraound in your case. environment: |
This one I have not seen in my system. I believe this is related to when something is rendered using Cairo but otherwise not quite sure. This one I know what the issue is and will fix it. I'm using hashes to give unique filenames to thumbnails and if hash starts with number then ffmpeg thinks we are trying to create a frame sequence video clip. I'll label this as a bug. Maybe fixing this will fix the one above too. These show up sometimes, but these are definitely in MLT or ffmpeg issues so I don't have any clear path currently in mind on how to move forward. wolfgangr above provided some additional info. I'll look if I see this, but I don't think it shows on my system. |
@wolfgangr thanks, I'll do some comparing with other MLT based apps to see if I'm indeed doing something wrong here or could MLt be patched to get improvement here. |
Pushed a patch to fix this complaint when creating thumbnails. |

On latest flatpak or my dev I'm not getting: which is not surprising,Flowblade does not use any xapp functionality, as listed here: https://projects.linuxmint.com/xapp/reference/index.html. I'm pretty sure issue is with Linux Mint 21.2 as libxapp readme says: "This project gathers the components which are common to multiple GTK desktop environments". That seems something that Mint could be using. |
|
Thanks guys for the good information and quick response. I can ignore the bogus warnings, but the crashes are quite inconvenient. I had another one yesterday, but I don't have any CL output since I started Flowblade from the Mint menu. |
|
I just had 2 crashes in short order. One was the common issue: But the second one was partially new: I know malloc() is a C function, and Python is written in C, but I have never seen a C error show up in Python crashes before. Perhaps a clue? |
|
I tried the ffmpeg code you gave to convert a short clip. I closed the existing project in Flowblade, the imported the converted clip. Inserted it 3 times on the V1 timeline and played it a couple of times. Split one of the clips, then deleted the 1st half. during playback I got another crash, different again: The converted clip played fine in both VLC and Flowblade. Maybe I did something wrong in the conversion. |
|
Can you try the Flatpak version: https://flathub.org/apps/io.github.jliljebl.Flowblade Linux Mint 21.2 Victoria should support Flatpaks and you can just press install on the webpage. |
|
I am using a Flatpack install, to get the latest version. I didn't use the one in the Mint repositories, because it was v2.8. But maybe something wrong with Mint's Flatpack version? I will try the one you suggested. |
|
Installed the Flatpack suggested above and all went well for a while, then another crash. It was preceded by many, many lines of the same |
|
Ok. Can you make one of the clips that cause the crash in your system downloadable somehow so I can try to reproduce the issue on my system? |
|
Yes, of course, here is a link to the last clip that I experienced a crash on: Just to be clear, the crashes seem random and not limited to this clip. Here is some information from Google Photos that may or may not be relevant: |
|
I don't mean to overwhelm you with data but I had another crash and looked at my logs. I thought it might be useful. Crash while editing a video with a dozen or so clips. Split a short clip (not the one I linked to in previous message), then muted audio in 2nd part. Crashed while playing: /var/log/syslog |
|
Thanks, looked at the clip. Didn't crash on first try. I'll do longer test later and try to play with it longer, add filters, use in on multiple tracks, split audio etc. to see if crashes start to occur. |
|
Thank you. I tried the open source video driver instead of the nVidia one.
Still had a crash. The nVidea driver manager has lots of settings, but I
don't understand most of them. I don't know if any of those would help
anyway.

A possible clue; I got a GoPro and have been using Flowblade to edit it's videos. No actual crashes yet but I did get 2 lockups and lots of error messages: Flowblade was then unresponsive for 3-5 minutes. Then, right clicking on the color clip and selecting Open in Clip Monitor, I get this error: Flowblade was again unresponsive, but for a shorter time. It never actually crashed in either instance. Note also that I am using GoPro clips |
|
Thanks, this a bug I can reproduce and fix, probably not related to the other Issue though. |
This is now fixed in repo. I did a longer edit with file the you send and got no crashes. The only thing that that seemed peculiar about the file was that it had speed marked as 29.86 fps, which is very non-standard frames per second value. I did a do a web search on the error message and in one seemed to be involved with some GTK locking issues, but that would crash always, not with just some files. I'll keep this open and see if we new get some ideas on what this is about. |

Thank you. Yes I noticed the frame rate, but didn't think anything of it. I
was always clicking yes to conversion on the dialog that pops up saying "A
video file was loaded that does not match project profile." . I tried NOT
converting with the GoPro footage that I shot at 1080p 30fps and it
crashed. Same footage, but letting Flowblade convert has not caused any
issues so far. Curiously, it shows 29.97fps. I thought this was close
enough, so I did not convert it the first time, and got a crash.
What distro do you develop and test Flowblade on?

Flowblade version: 2.10.0.4
MLT version: 7.17.0
Distribution: Linux Mint 21.2 Victoria
what is happening.:
Crash playing video after adding title. Did not crash at the title though:
Another crash viewing clips on timeline, just after creating a title:
Lots of this in command line output even if no immediate crash:
[mp3float @ 0x7f7329f7e300] Could not update timestamps for skipped samples.Viewing clip that was sped up 25% in viewer:
I always get this message on startup:
Gtk-Message: 12:54:20.512: Failed to load module "xapp-gtk3-module"python3-xapp v2.14 is installed however. I tried:
"sudo apt install --reinstall gir1.2-xapp-1.0 libxapp1 xapps-common python3-xapp"
But I still get the same error message.
Sorry about the previous lack of formatting.
Thank you for creating this great application! I toy with Python programming and I can't imagine the complexity of code this must take.
