AW: filesink with 60 fps

[Bernhard Graaf]

Try to use ‚gst-launch-1.0 –e’ to send the eos-signal to the pipeline. Then
the timing information should save to the file.

Nicolas,

 

Thank you so much! Now I'm able to encode and play streams with any desired
framerate.

But I've noticed one strange thing. When I open the generated .mkv-files
with VLC (or any other player) it can't recognize its duration.

In opposite to this behavior, when I encode .mkv from bare H264 bytestream
with x264:

x264 --crf 18 -o output.mkv video.h264

I'm able to see proper duration and progress in any media player.

I have already tried all parameters of the x264enc and matroskamux elements.
But nothing changed )

 

Thanks,

Ilya

Bare H264 bytestream have no time information. Use a container like
MP4, MKV, FLV, TS, etc in order to store you videostream with
appropriate time information. As an example:

gst-launch-1.0 ksvideosrc ! image/jpeg,width=1280,height=720,framerate=60/1
! jpegdec ! videoconvert ! x264enc ! matroskamux ! filesink
location=video.mkv
