Batchrender patch
by Andrea paz 21 Jun '26

21 Jun '26

I was wondering if Andrew's patch for batch rendering (batchrender_postmerge_xml_check.diff) is already in Git. Even though it fixes a very rare issue, I think it's useful because it prevents us from corrupting the (non-XML) file we're targeting. I recall that if we run a command-line render and mistakenly target any file other than the XML project file, that file gets completely corrupted. PS: It seems to me that it also handles simple command-line rendering, not just batch rendering.

Surprising to see Cinelerra mentioned in AI

I realize that most people do not like Google's AI output when you do a search, but I was surprised to see mention of "Cinelerra" in the output when I did a lookup of "AudioOSS::open_output: No such file or directory". P.S. I made the Cinelerra below in Huge letters just so it would stand out. AI Overview This error usually means the application is trying to use legacy Open Sound > System (OSS) drivers, or an audio device is missing or misconfigured.

mjpeg capture from webcam

Hello all! I am not dead, just playing around with my old new powerpc toy ;) Unfortunately big endian machines quite rare thing today so some bugs creept in. But after filing some bugreports I decided to see how it works with my yesteryear webcam. Well, default ffmpeg -i /dev/video0 uses uncompressed YUV2 stream and framerate drops to 10 fps for 720p and to 5 fps for 1080p ffmpeg -s 1920x1080 -pix_fmt mjpeg -i /dev/video0 -c:v copy -f mov -frames 900 ~/camera.mov this line one the other hand captures at 50 fps, 12.6 mbytes per second ;) I really need to fix our mjpeg capture ...

More big endian fixes ?
by Andrew Randrianasulu 05 Jun '26

So I was having a blast (esp. in open firmware ;) ) with my new G5. Compiled Cinelerra-gg on Slackware ~current ppc32 (gcc 15.2.0). But sadly sound was broken? I suspected ffmpeg but even native way sounded wrong, but rendered correctly?! Turned out both ALSA and Pulseaudio hardcoded LE variant, and at least on Slackware alsa offered BE variant - picked by speaker-test utility. I added code to use this or old variant depending on BC_Resources::little_endian and it seems to sound fine now on both outputs? Can you please test on le ? (usual intel/arm)
