[07:36] <Guest11536> Hey guys, [07:36] <Guest11536> I'm building an android application, and I need to use some ffmpeg commands. [07:36] <Guest11536> I've got a source video and I need to edit it: [07:36] <Guest11536> 1) Cut only the last 7 seconds. [07:36] <Guest11536> 2) Add a watermark(logo) on the top left side of the video.(00:00-00:07) [07:36] <Guest11536> 3) Add a video inside the source video on the bottom right side of the video.(00:00-00:07) [07:36] <Guest11536> 4) Add another video to the edited video from steps 1-3 (00:07-00:10)\ [07:36] <Guest11536> Can I do it in one ffmpeg command line? [07:36] <Guest11536> What do I need to consider when I'm editing a video for a cellphone (quality,sizing..)? [07:36] <Guest11536> Thank a lot! [12:15] <Slev> hey, i am trying to send multiple mp4 files to an rtmp stream, one after one.. i somehow fail, is concat the right function? [15:27] <jnvsor> So when I stream to twitch with `-g` to set iframe interval it drifts upwards more and more as the stream goes on. Any ideas? [15:30] <BtbN> drifts upwards? [15:33] <jnvsor> BtbN: I set `-g 48` so every 2 seconds (With `-r 24` for 24fps) [15:33] <jnvsor> Twitch over time warns me that my keyframe interval is 3 seconds, 3.5 seconds, 4 seconds etc [15:33] <jnvsor> the longer the stream goes the bigger the interval becomes [15:34] <Mavrik> -g will never drift upwards [15:34] <Mavrik> are you losing frames by any chance? [15:35] <jnvsor> Possibly, but I can't tell. How would I find out? -v debug? [20:21] <DX099> hello all. How may I solve this ? [20:22] <DX099> "http://paste.ubuntu.com/7204380/" [20:24] <klaxa> install libopus-dev [20:27] <DX099> klaxa, I compiled opus... Isn't that enough ? [20:27] <klaxa> did you install it? [20:27] <klaxa> if so, where to? [20:29] <llogan> the ffmpeg install guide adds the path containing opus.pc to PKG_CONFIG_PATH [20:29] <llogan> http://trac.ffmpeg.org/wiki/UbuntuCompilationGuide#ffmpeg [20:30] <DX099> klaxa, to a build directory : http://paste.ubuntu.com/7204418/ [20:30] <DX099> llogan, and that exactly what I did I recon... [20:31] <klaxa> ah... hmm... that looks weird indeed [22:46] <Fumon> Is there an easy way to translate the output of ffprobe to a matching set of output configuration flags for encoding with ffmpeg?
