Summary0000346: The image disappears when a project including a trancoded source is reopened.
DescriptionThe transcode test project I did with the problematic source provided by Andrew works well when creating the project, but:

If I order the transcoded version of the file, without removing the original of the project, but only use the transcoded version.

I place the transcoded version in the Viewer, it is easy to view. I drag the source directly onto the timeline, it behaves well there and I can view all the parts I want in the composer.

If you save this test project and then re-open it, only the first frame is visible in the viewer and the composer, most of the timeline images are no longer displayed, only the sound still plays normally.

If I put the transcoded version back into the viewer, it now displays correctly and the composer plays again the selection I make in the timeline, but the missing images are still missing from the timeline.

If I delete the contents of the timeline and re-drag the transcoded source, everything comes back in order. But even if I save these changes to the project, the next time I reopen... the same problems are back.
TagsNo tags attached.

vdpau is the culprit!

After removing.bcast5 folder, I only added the:


To the new.bcast5 folder created, otherwise basic

At that time the problem of missing images from the transcode test with Andrew's problematic file was gone.

I then undertook to change the preferences one by one, checking each time after a CinGG restart that the problem described regarding Andrew's file did not return.

I first chose the X11-OpenGL video driver, then I increased the cache size to 1024.

I restarted CinGG and there was still no problem with Andrew's file.

Then I chose the HW Device vdpau.

Then I relaunched CinGG....

 The same problems with Andrew's file are back....

But, if I remove vdpau, the problem disappears.

vdpau is the culprit!

palette.dat is for choosing colors like in the Title plugin for your characters and outline colors. It is not that important but if you had a certain color of red you like to use, it will still be in the color wheel choice in the lower left hand corner.

I am surprised that Cinelerra_rc had to be deleted also and do not have a clue as to why that would cause a problem.

Thank you Phyllis for the information on the strings to keep.

I did it but I couldn't keep "Cinelerra_rc"; if I keep it, the problem described remains.

If I only keep it:

I have to readjust CinGG, but the problem described is fixed and I get my Layouts back which is very appreciated.

Question: What is "palette.dat" used for?

@Pierre, thanks for testing in the first place and for the final followup.
Maybe before making the drastic step of throwing away the .bcast5 folder, you could delete all of the files there, EXCEPT:

That way you would not lose so much of your configuration. If that does not solve the problem then you can still delete those too. However, this does not mean that there is still not some kind of bug in the first place -- some file must have been corrupt.

I will close this issue in a day or 2 in case anyone wants to add anything.

Problem solved.

I did what I don't like to do (because I then have to reconfigure CinGG to my liking in the preferences), I threw away the".bcast5" folder.

Then the problem of missing images from the transcode test with Andrew's problematic file is gone, everything works fine now.

@Olaf -- "I don't see anything problematic about Andrew's video, it's an ordinary DV/PCM in an AVI container."
If you play from the beginning it works fine as is. If you move the cursor to further down and try to play, the audio no longer plays correctly. I think this is described in BT 0000330. A patch was created for these types of files for Andrew to use if he wanted to BUT this patch is not going to be checked into GIT because the philosophy is that it is better to fix files that have problems rather than have Cinelerra compensate for every thing that can go wrong!

I don't see anything problematic about Andrew's video, it's an ordinary DV/PCM in an AVI container. The transcoding went smoothly and even after repeated opening I can't see any misbehaviour. And even if it's exotic material, the transcoding is meant to turn problematic raw material into editable material. This should not be confused with the use of proxies. Lossless or optically lossless codecs are usually used for this purpose. What do you use?

By the way, the attached MediaInfo excerpts show that the scan type is written from Interlaced to Progressive, although the project was set to Interlaced before transcoding and the material is not DeInterlaced after transcoding. Any tips?

@Pierre - I still am not able to create the problem that you see. The reason the source file has a default tag of "convert" is because when the menu comes up, the Tag suffix box has ".convert" in it from before the change to transcode was made. That Tag suffix was saved in your preferences when you tested the original version. So you have to manually change the Tag suffix testbox to get it changed from now on to .transcode or whatever you want instead. We wanted to make the Tag suffix settable by the user in case there was a name conflict or language issue.

Yes, if I use files of my own that do not have any problems running in CinGG, the problem of maintaining images when reopening is not present; everything is normal.

The problem described (loss of image on reopening) only seems to occur with Andrew's problematic file Isn't this the very reason Transcode exists, to facilitate the use of such problematic sources?

Another thing I noticed now that I have In the preferences deleted all existing indexes and thumbnails, every time previous projects open, it re-indexes the sources... each time. This, even though I increased the size of the index files to 163840 KB (about 10x bigger) instead of 16384 KB.

I have tried too but with my “.mov” videos source and transcoded in XviD on UbuntuStudio16.04, and like Phyllis and Olaf, it works.

May be that it depends from the type of the transcode format?
Are you (Pierre) tested with your own files, before?


2019-12-04 14:19

updater   ~0002530

The same problem occurs if I reconstruct index (by lmb) from the convert source

I also rebuilt the test from the beginning from the file by Andrew

I checked in the preferences menu that the size of the index files is 16384 KB

In the preferences I deleted all existing indexes and thumbnails.

Same problems....

I noticed that even if the function is now called "transcode", the source file created always has by default a Tag".convert" instead of .transcoded, is that correct?

I have tried to recreate this with my own footage (mp4/mts to ffvhuff/mkv), unfortunately unsuccessfully. In this relationship everything behaves as it should. Will the index possibly be lost? Maybe increasing the size of the index files will help? I use 16384 KB on an own SSD. But I can't say from a distance if this is the reason.

I have not been able to reproduce when I transcoded to ffmpeg / mp4 following your steps. Most likely the problem is that a "rebuild index" may be required. Try lmb (left mouse click) in the Resources window / Media folder on the LD...transcode... file and select the 4th option of "Rebuild index". Then save project with the transcoded file and try to re-open and check to see if you still have the same problem. Rebuild index often solves problems.

Meanwhile I will continue to try to reproduce the error and see what can be done.
