Optimize the Seek Method
Even though seek () is the common approach to get directly to the designated spot on the video; however, this may result in choppy playback if the underlying mechanism for the video is not well optimized for seeking. There are some recommendations in this respect:
Buffering and Caching: Add a buffer to the video player that is set to a certain number of frames before the current position. This can facilitate seeking and make the movement more seamless.
Use a Separate Thread: When there is a need to perform seeking, do so in a different thread so as not to block the primary UI thread. Clock.schedule_once function in Kivy is able to manage UI updates thanks to its ability of scheduling the updates without pauses in video playback.
Implement Smooth Seeking
Instead of jumping directly for fast forward and rewind, create a way of seeking that is smooth and transitions gradually:
from kivy.clock import Clock
class VideoPlayerApp(MDApp):
Existing methods…
def seek_video(self, delta):
Calculate new position
new_position = max(0, min(self.video.position + delta, self.video.duration))
self.video.seek(new_position)
def rewind_5s(self):
self.seek_video(-5)
def forward_5s(self):
self.seek_video(5)
3.Associate Responsiveness with Button Presses.
Make sure that the button responses are quite seamless in execution:
Typical Debounce Button Presses: This is the responsibility of the mechanic engineer as he/she will be compelled to add a gradual switch to avoid surge in the button presses.
def on_rewind_press(self):
if no self.is_seeking:
self.is_seeking = True self.rewind_5s() Clock .schedule_once( lambda dt: self.reset_seeking(), 0,5 )
def reset_seeking(self):
self.is_seeking = False
Ffplyayer Features.
Place a check on FFpy - Player documentation for feature pointers that may help handle video rendering in a better way :
Seek Precision: Some players have the option of seeking and controlling which specific parts of the video to seek (e.g. keyframe seeking vs timestamp seeking) thus ensure you get the ideal user practices for their specified needs.
Error Handling: Handle your seek calls with appropriate error handling measures so that you cover for any unexpected behavior.
Log Seek Operations: However, to understand why the video does occasionally hop erratically, add logging around your seek calls to capture the current position before and after seeking.

Alternative Libraries
Nonetheless, if the issues still stick, you might want to try other libraries:

It is a very powerful multimedia framework which might outperform the seeking and playback centered sections.
Conclusion
Following through those bullet points, targeting optimization to the largest performance bottlenecks moving part of seeking implementation, handling responsiveness of buttons considerably better and looking at other libraries if necessary means you can safely boost greatly the performance of Kivy video player. Testing and debugging with logging will also help in determining the specific issues and enhancing user experience.
