ges-launch tutorial

[Vincent Achard]

Hello

The actual https://gstreamer.freedesktop.org ges-launch tutorial says:

"ges-launch-1.0 +clip /path/to/media inpoint=4.0

Assuming "media" is a 10 second long media sample, this will play the sample from the 4th second to the 10th, resulting in a 6-seconds long playback."

However, my experience is:

ges-launch-1.0 +clip file.ogg inpoint=2
>>>fails with error: ERROR: Could not create timeline because: Couldn't add clip with id file:///path/to/file.ogg to layer with priority -1

ges-launch-1.0 +clip file.ogg inpoint=2 duration=2
>>>succeeds (I see the preview with correct cut)


file.ogg contains one video/x-theora stream and is 0:00:24.024000000 long


looking through the debug log I find in the case that fails :

0:00:00.140059961  3054      0x111ce30 INFO                 gestree ges-timeline-tree.c:403:check_track_elements_overlaps_and_values: videourisource0<0x12ea190> [ 0:00:00.000000000 (0:00:02.000000000) - 0:00:24.024000000(0:00:24.024000000) layer: 0]  inpoint + duration 26024000000 > max_duration 24024000000


my guess is that the default duration is the total length, therefore an inpoint > 0 will result in failure

indeed:
ges-launch-1.0 +clip file.ogg inpoint=0
>>>succeeds

I am using a self compiled 1.16.0 gstreamer version

am I missing something?

or should the tutorial be modified, as this is misleading (and it's one of the first examples: newcomers could want to run away?)

please apologize for my bad english, and if this is not the right place to post

cheers!

Vince

Hi Vince,

This is indeed an error in the documentation, we need to specify the duration if we specify the inpoint right now, we could handle that in a better way in ges-launch but for now, could you make a patch to update the documentation?

BR,

Hi again,

Actually this has been fixed in master: https://gitlab.freedesktop.org/gstreamer/gst-editing-services/merge_requests/89/commits

This is gonna be cherry-picked in the next 1.16.X stable release.

Regards
