Question / Help Works Like a Charm

Well, under kubuntu 14.04 with proprietary Nvidia drivers...

OBS works like a charm! Fantastic! I haven't messed around with a ton of options (because I know many are missing/non-functional), but basic desktop recording with desktop audio and a mic work fine.

My only question at this point, and I'm sure its one that has been asked elsewhere, but: why is flash video the only output option? Are other output options (such as h264) planned? My windows PC uses OBS to record with h264 crf=22. Makes things easy for file output, and I don't have to worry that my bitrate is high enough (or too high). Can't wait for the option to do the same thing on the linux PC!

Thanks a lot Jim, and the rest of the hardworking team!

The FLV files already are h264/AAC. I haven't put in the advanced options yet

FLV is just a container for an h.264 video stream and AAC audio stream. You can convert it to MP4 quite easily. Here is a guide: https://obsproject.com/forum/resources/how-to-convert-flvs-to-mp4-fast-without-re-encoding.78/

OBS will have many more output options in the future, but it is still pretty early in development, of course.

Curious as to why FLV was used as the container instead of MP4. Looking forward to future versions, but until that time this will suffice nicely for recording linux howtos easily. Thanks again!

If recording is interrupted (e.g. a program or system crash) MP4 tends to be unrecoverable while FLV is much more resilient. I think at one point the plan was to always output FLV initially and then remux if a different container is desired, but I'm not sure if this is still the case.

We're going to program it to pipe to a separate child process to safely ensure that MP4s can't be damaged if the program crashes for whatever reason. We just haven't written it it. In the time being however, if you need MP4, the FLVs can be remuxed with FFmpeg.

ffmpeg -i [input file].flv -acodec copy -vcodec copy [output file].mp4

Thanks. I don't think I'll need MP4s. KDENLive can view just about anything you throw at it, regardless of the container. I was merely curious. :)
