Summary: Memory leak when playing or editing clips in a 720p HD
project
Product: Cinelerra
Version: 2.1
Platform: PC
OS/Version: Linux
Status: NEW
Severity: major
Priority: Medium
Component: User Interface
AssignedTo: [email protected]
ReportedBy: [email protected]
In preparing a video for YouTube HD from video, project is 1280x720, 29.97 fps
YUVA 8-bit, non-interlaced, 44.1kHz 2-channel audio.
Clip #1 is an NTSC DV file from camcorder via dvgrab. Clip #2 is a desktop
screen capture at 1010x606 in mjpeg AVI format (in a MOV container) converted
from AVI format from Windows using mencoder. Clip #3 is a 2-channel 44.1kHz
AIFF.
Editing or even just playing the timeline with the clips overlaid causes
Cinelerra to quickly (within 2 minutes) consume all available system memory and
swap.
This did not happen when using the same exact clips and arrangment in an SD
NTSC project (720x480, 29.97fps, non-interlaced) format. (I would just use that
but I lose the wide-screen advantage of the desktop capture.)
System is a dual dual-core Opteron 270 HP xw9300 workstation with 2GB RAM and
2.5GB swap.
Reproducible: Always
Steps to Reproduce:
1. Create project of size 1280x720, 29.97fps, non-interlaced
2. Import video clip of non-standard size, like 1010x606, and one standard
720x480.
3. Place them both on the timeline in separate tracks
4. Play the timeline. Notice that memory gets gobbled up until your system
begins to thrash.
Actual Results:
All available system memory and swap was consumed within 2 minutes.
Expected Results:
Consume only the memory needed at any instant and free it shortly after
finishing with it.
SUV theme. The odd-sized clip is the problem. If I delete that from the
timeline, the problem goes away.
