Andrew,
I have my .bcast5 folder on relatively slow STA HDD (not SSD), formatted for /home as xfs. may be slow access to indexes caused/exaggregated this bug?
Can you try with index placed into slow place/disk, or inside VM?
We were hoping your suggestion might show us the error as we tried using a VM (xen which is quite slow).
Also, is there anything I can poke with gdb?
1. Can you apply the attached patch and see if that provides more helpful information? The patch was applied here on the cinelerra ffmpeg 4.2 version (but gg says should work on any version). You might want to redirect the output as it is voluminous on the print out. The last thing you should see before cin hangs is "clear" and then "boom" it is hung. This last thing may give us a clue. Please use the same 2 files as reported in your initial June 5th sample (the hell and kara ones).
Unfortunately right now it hangs even with just one file (1 video, 2 audio tracks) Sorry if I was not very clear, hang _probably_ not originated from ffmpeg - as I just found out, but it still present even if assertion at reloading (dnd from resource window to timeline) media still fires for me if I set CinGG's git to something recent. So, probably assertion is one bug, and hang is another.
2. Can you send us a session file (using the same 2 input files) and your .bcast5 file?
There is no session file per se I just 'O' for opening file, select it via file selector window, with startegy set to 'create resources only' After this I drag video from 'resources' into timeline. With cinGG git and any version of ffmpeg it will fire assertion at threading in ffmpeg IF I try this operation few times (2 or 3). If I avoid this assertion by setting CinGG git to commit de541aa9508555c35ea284d5b03617fc9c7cd026 then I still have hang on just deleting any portion of project, by just selecting region with mouse and hitting 'del'
3. Are you using hardware (vaapi or vdpau)? Are you using OpenGL or just X11?
No, just OpenGL/X11 Attached Cinelerra_rc, because .bcast5 folder currently full of index files ... I can clean it up, but first I hope to reset CinGG back to head and recompile, so I'll get assert back
The 1 time gg finally managed to create the problem last week was with 4.2.3 from GIT and now he is no longer able to do so. We have tried all kinds of variations to exacerbate the problem and got nothing today. Tried: laptop, desktop, fewer cpus (down to 2), switched in settings to x11 or OpenGL, tested with vdpau, put the cache in settings down to 256, started out with no .bcast5, ran by exporting the Display and actually running as an ordinary user without debug, ran with Valgrind (again to slow things down), 2 different versions of Fedora, Debian 10 (since that is what RafaMar's user was initially using), cut the end off of "hell...mkv" and then redo and cut again over and over and over and over...
Log file also attached, while I'm not sure if it really helpful in any way (because with my git state I get hang, but not assert ....
