Mov file generated does not play on QT player

[Irfan Shaikh-2]

Hello all,

          MOV file generated by gst-ffmpeg is not able to play back on QT. Is any specific atom missing. I am only observing the seek baar moves ahead, but the playing FPS in movie inspector is alwayz zero.  actual fps of file in 30 in movie inspector.
          Does QT requires some specific info. "Generated file plays good on VLC Player"

Regards

Maybe you could mention the exact pipeline/elements you used to create
that file that doesn't work properly? And what versions of the various
modules/elements you're using? And if you're using mp4mux or ffmux_*?

Cheers

Thanks. However, that doesn't tell us what versions of things your are
using, which I also asked for.

It seems you are using a ffmux_* muxer. These muxers are not
well-supported by gst-ffmpeg, you should always use the 'native' muxer
if there is one.

Have you tried a recent version of mp4mux from gst-plugins-bad?

 Cheers

You will probably have to use h264parse output-format=sample access-unit=true in
both cases, as mov does not really have a taste for bytestream NAL units (and
would also be missing codec-data and corresponding track metadata), and QT
player even less.

Using a recent mp4mux/qtmux (as suggested) would likely also make the necessity
of the above clearer (by means of caps).

Mark.

Thanks a lot,

 It started working on QT player after adding "output-format=sample access-unit=true"
