Summary: x264 fails when rendering to a h264 video; prints "x264
[error]: no ratecontrol method specified" and then
segmentation faults while GUI hangs forever
Product: Cinelerra
Version: 2.1
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: Medium
Component: Rendering
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
I am using Ubuntu 8.04 with all the latest updates installed.
cinelerra --version prints:
Cinelerra 2.1CV (C) 2006 Heroine Virtual Ltd.
Compiled on lun giu 30 11:09:09 UTC 2008
This used to work up to roughly May 2008. Then an update caused the problem.
I open a trivial project (e.g. just a png image) and then I try to render it
with container "Quicktime for Windows" and video stream set to "H.264".
The GUI hangs forever. On the xterm it prints:
cinelerra Template.cinelerra.project.080307.xml

The key lines are:
x264 [error]: no ratecontrol method specified
signal_entry: got SIGSEGV my pid=29941 execution table size=16:
I searched on Google and found that the x264 lib has changed and that the rate
control parameter was optional in the past and is now a required parameter. I
suspect that this causes the problem (that cinelerra does not pass the now
required rate control parameter to x264).
I have the latest Ubunti libx264 installed:
libx264-57 x264 video coding library 1:0.svn20071224-0.0ubuntu1
As I said, this worked in the past.
Reproducible: Always
Steps to Reproduce:
1. create a very simple project (anything to render, e.g. an image)
2. go to File menu, chose "Render"
3. select "Quicktime" as container and H.264 as video stream, and MP4 as audio
stream
4. click "OK" to render
5. it hangs at 0% forever, look at the xterm console to see the error msgs
Actual Results:
GUI hangs. Xterm prints stated error message. No video is rendered. A useless
16-byte output file is created instead of the expected video.
Expected Results:
Video rendered and a valid video file created.
