  • Possible to apply renice on a single process in fluent-ffmpeg ?

    12 novembre 2015, par pkeuter

    In the readme of fluent-ffmpeg I see it’s possible to renice ffmpeg. Since I am using multiple instances, I was wondering if it’s possible to renice a single instance of ffmpeg, using fluent ffmpeg.

    renice([niceness=0]) : change ffmpeg process priority

    This method alters the niceness (priority) value of any running ffmpeg
    process (if any) and any process spawned in the future. The niceness
    parameter may range from -20 (highest priority) to 20 (lowest
    priority) and defaults to 0 (which is the default process niceness on
    most *nix systems).

    Does anybody have an idea on how to do this ?

    Fixes apparent mmal_port_disable() freezes in ffmmal_stop_decoder() when
    
calling ffmmal_decode() with flush semantics a large number of times in

  • Capturing two video sources into a single MKV with Java

    7 avril 2014, par Luke

    Problem

    I need my application to let the user record its screen, web cam and audio simultaneously. I have been able to accomplish this using a mix of Sarxos, Robot and Xuggler. But the various output files have different timing and are out of sync when played back synchronously.

    This is not hard to imagine given that the capturing is started asynchronously.

    Possible solution

    I'm thinking that capturing the various sources into an MKV file with multiple video tracks might be a better solution. Some timer could poll the sources in parallel at regular intervals. Or at the very least blank audio/video-data could be inserted before any late capture start, to keep the video's and audio in sync.

    JMF would allow for very easy capturing, but doesn't seem to support MKV and is supposedly very outdated. I question whether it will work properly on current PCs and Macs. The FMJ Project might be an alternative, but MKV-support seems to be restricted to FFMPEG. This would defeat the purpose, as any kind of muxing or re-encoding afterwards would still leave the videos and audio out of sync. I could use Xuggler, as I do now, but it's impossible to find any relevant documentation or hints.

    Still, recording into a single file seems to make sense in order to get the timing straight.

    My question

    Is anyone aware of a Java solution that would allow for encoding two video sources and an audio source into a single MKV container ?
