Can you provide a video sample (1 minute recording) of this HD+ (1600x900) format? Or download link to legal publicly available video
I can not find any downloadable sample/demo video. I want to test if this issue is present here. Could be the 1600x900 HD+ plus resolution is causing a problem (not standard video format?)

[magic75]

I am able to reproduce the same crash with Kazam screen recordings in H264 format, using your 64bit Ubuntu build 150502.

[Jan Gruuthuse]

Something did change in relation to kazam recording: did try to visit their homepage and it is no longer there. Have a simular issue here. (presumably colorspace?)
Kazam records in AVC High 4:4:4 Predictive@L4.0, perhaps the developer(s) have a solution for this.

Otherwise a user solution is: switch to Maarten Baert's SimpleScreenRecorder this records in AVC High@L4.0
And is handled correctly by avidemux. sample recording 1.1 MB <- click

[mean]

would need a sample
even 5 images long

[Jan Gruuthuse]

as requested kazam desktop recordings 1600x900
- 4.4 MB KazamH264-1600x900.mp4
- 1.2 MB KazamVP8-1600x900.webm

webm VP8 has several libvpx issues in avidemux see attached screenshot.
- UV swapped
- Does not play in player
- when Color filters swap UV is applied and saved while reencoded the video is processed correctly.

[Jan Gruuthuse]

webm VP8 libvpx issue - Does not play in player is fixed/no longer there with build d7869cb 04 may 2015

[mean]

should work now, windows build in progress

[Jan Gruuthuse]

lavcodec = OK

[Jan Gruuthuse]

vdpau = player shows green screen/or image from previous video (buffer?)
see attached terminal output
