Description Baldur Gislason 2012-10-18 18:46:20 UTC
Some of the MXF files I open with mxfdemux do not link up. 
I may execute something like
gst-launch -v filesrc --gst-debug-level=5 location=283267.mxf ! decodebin ! video/x-raw-yuv ! fakesink
and the pipeline will not link up. Looking through the output I may see messages like "No essence track for this essence element" which don't appear when the playback works.
File format is:
Video codec: IMX(D-10) 30 Mb/s, 720x608, 25 fps, upper field first
Audio codec:  8 Channel PCM, 24 bit, 48khz
Wrapper: MXF OPa1

Output from gst-launch:

Comment 1 Baldur Gislason 2012-10-18 20:16:48 UTC
I should add, ffdemux_mxf finds the video track but has trouble with audio.
Comment 2 Sebastian Dröge (slomo) 2012-10-19 09:51:15 UTC
This MPEG2 mapping is not implemented in mxfdemux yet. Someone needs to get the spec and implement it, like the other mappings already there
Comment 3 Baldur Gislason 2012-10-24 13:15:37 UTC
I'm still a little confused by the construction of the mxfdemux, where in the code is the mapping specified, and what spec do I need to make it work?
Comment 4 Sebastian Dröge (slomo) 2012-10-24 13:29:14 UTC
Judging from the video codec information you mentioned above this should be in SMPTE S386M-2004. But mxfd10.c already implements that, so it's probably just missing something for this specific variant.
Comment 5 Vincent Penquerc'h 2017-05-16 10:10:57 UTC
The file is inaccessible now.
