How to get support video codec in rvio

I've tried rvio -formats, but it only list support file formats.

But I still don't know what can I type after -codec to specify video encoder.

Is there a list about this?

    Hi Changlin,

    The output from -formats is the list, but it is formatted a little awkwardly as it gets generated somewhat programmatically. In particular when output from the documentation we gather has newlines and is not properly indented. It is also very lengthy and repetitive. I would suggest saving it to a searchable output file and then searching for the codecs you are interested in.

    If you are comfortable in a shell like Linux and Mac have than you might use my method to search the output like so:

    bash:

    rvio -formats 2>&1 | less

    tcsh:

    rvio -formats | less

    then I can press "/" and enter text to search for.

    What codec are you looking for and on what platform/RV version combination?

    Thanks,

    Jon

    I want to use mpeg-4 or prores when encode to mov.

    The "-format" command shows only the file format, I can't even find x264 (the only codec I found) in it.

    I use rv 3.12.19 on Ubuntu 10.04 64bit.

    Hi Changlin,

    If you search for "image codecs" you should see the list. We always recommend "jpeg" (photo jpeg) which is the default for playback performance, but it does create larger files.

    As you saw "x264" is in there and is popular for people looking for H264 output on linux. I see something listed as "ffmpeg_mpg4" which appears to be an MPEG-4 codec. Have you tried that?

    We do not have a way to do ProRes on linux at this time.

    Please let me know if that works for you.

    Thanks,

    Jon

    Thanks, this is what I want.

    BTW, when I use ffmpeg_h264, it will appear warning and errro like below:

    WARNING: quicktime codecs: quicktime_encode_video_stub called
    WARNING: quicktime codecs: quicktime_encode_video_stub called
    ERROR: MovieOQT: quicktime encode failed at frame 1

    Is there any solution?

    HI Changlin,

    I will look into that. Thank you for the report. In the mean time you may want to try using "x264" to get avc1 encoding.

    Thanks,

    Jon

    Hi Changlin,

    Thank you for the link. I suspect since we got things working with "-codec x264" for those looking for H.264/AVC1 encoding I think ffmpeg_h264 may have never been completed. But like I said I will take a look and let you know.

    Thanks again!
