i'm having some troubles in a script that use the auto detect features function from the tracking layout. The above script return the error:

RuntimeError: Operator bpy.ops.clip.detect_features.poll() failed, context is incorrect

Does someone knows how to force a change context to clip tracking?

import bpy
import random

scene = bpy.context.scene

bpy.ops.clip.open(directory="/home/lucasa/Vídeos/", files=[{"name":"100_0921.MP4", "name":"100_0921.MP4"}], relative_path=True)
print('video clip imported')

clip = bpy.data.movieclips[0]
print("\nMovie Clip %s" % clip.name)

bpy.ops.clip.detect_features()
print('\nDetect Features')

I know this is years late but I will answer this incase anyone stumbles across this.

In this case you need to force context since the operators require a certain context to execute. To do this for the detect_features method you can do:

ctx = bpy.context.copy()
for area in bpy.context.screen.areas:
    if area.type == 'CLIP_EDITOR':
        ctx['area'] = area
bpy.ops.clip.detect_features(ctx)
