  • Duplicate outputs using JavaCV

    17 octobre 2015, par bickster

    I want to use JavaCV to both live stream a video over RTMP and save it to a local file on Android. I can do both independently, but it is very inefficient. This link on ffmpeg suggests that it is possible to do it at the same time to avoid the encoding of the video twice. https://trac.ffmpeg.org/wiki/Creating%20multiple%20outputs

    How do I enable this functionality in JavaCV ?

  • What's the difference with crf and qp in ffmpeg ?

    18 novembre 2016, par Nova

    After browsing around Google, I’ve came across this page about h264 encoding and discovered about qp. https://trac.ffmpeg.org/wiki/Encode/H.264

    My questions are : What are the differences with crf and qp ? Is it better to use qp over crf overall, or is it only if for using qp 0 for best lossless ? Does qp have a known sensible setting if it’s preferred ? So far, I know crf has the default value of 23 while 18 is a sensible preferred increase in quality, although I don’t understand why 18 wouldn’t be default if better sensible lossless. Lastly, would changing either of them cause incompatibility with non-ffmpeg players or just qp ?

    I’m converting from webm to mp4 by the way.

    I was going to test crf 23 and 18 and pick which is best but I can’t seem to find any concrete information on this comparison or about qp.
