Media Branch - Success with Recording

1

Hi all,

I wanted to report that I was able to successfully compile the media
branch, and did my first recording. It works!

There were absolutely no issues. Code compiled cleanly and the BasicExample
worked to the spec. I will upload some of the recorded videos (need to
convert them from mkv to mp4) to dropbox or other share sites soon.

Congratulations are in order for the Licode team for their excellent work.

Best Regards,

John

Hi Pedro,

Thanks for your suggestion. I am converting mkv to webm using one of the
following commands:

ffmpeg -i /tmp/xyz.mkv -c:v copy -b:v 60k -c:a libvorbis /tmp/xyz.webm
or
ffmpeg -i /tmp/xyz.mkv -c:v copy -qscale:a 6 -c:a libvorbis -f webm
/tmp/xyz.webm

Only problem I am facing is: Sometime transcoded video doesn’t play on
Google Chrome. However it always works on Firefox. Looking at the ffprobe
doesn’t give any clue. Can you help me understand, why it is happening
intermittently? And it would be great, if you could suggest me some
solution.

Thanks,

Hi!

John, We are happy to hear it worked for you :slight_smile: As you say, the container
used is mkv as we are using vp8+pcmu8 and is the only container we could
use at this time. However it is quite easy to transcode it to mp4/webm with
avconv/ffmpeg. Going to webm is superfast as you can just copy the video
stream and encode the audio.

@Dennis: In our tests it worked flawlessly with Firefox. We will try to
keep this branch up-to-date with the cleanup branch.

We are expecting some problems when recording in lossy/low bandwith
connections, in our tests video glitches/audio cuts appear, we are working
on it.
Please share any issues you have, we still have some improvements to make
and all the information we can get is really valuable.

Thanks to all of you in advance! :smiley:

Cheers!

Hi Pedro,

Definitely will be testing and posting issues as I uncover them. BTW,
tried covering the mkv to webm using the following command with no luck.

avconv -i recording88410590961575500.mkv -acodec vorbis -strict
experimental test.webm

Can you share the right command for conversion please.

Thanks.
