Mezzmo Media Player is jittery and glitchy on Amazon FireTV & FireTV Stick

The FFmpeg information appears to be missing the stream information, possibly Mezzmo did not wait long enough to get it, can you please try getting the FFmpeg information again to see if the stream info is added?

[Peter]

Thanks, nothing in the FFmpeg information really jumps out at me so it is possibly an encoding issue. Could you please try pre-transcoding the file and force a full transcode to see if this allows the video to play smoothly? We will try a similar file here to see if we can reproduce it on our Fire TV Stick.

[Fleenor50]

I pre-transcoded the file using the Mezzmo (android) device profile, but the problem is still there. I even replaced the original file with the transcoded one to make sure the newer one was playing.

Here is the FFMPEG for the transcoded file:

[Peter]

I tried streaming a similar movie here to our FireTV and it did not have the issue during the panning sequence at the start of Secret Life of Pets. It was a lower resolution version so possibly this was why. Could you please try making a sample of the first ten minutes of the movie and then send it to us at support [at] conceiva [dot] com. To create a sample please see https://superuser.com/questions/3773...on-with-ffmpeg

[smitbret]

Finally got around to testing the HW/SW decoding on both the FireTV and the FireTV Stick. The FireTV Stick lacks the resources to playback my large BD rips with the SW decoder so it was just a jumpy, pausing mess. However, playback on the FireTV Box with the Software decoding was smooth, the way I would expect. Turning the HW decoding back on and it gets jittery again.

[Fleenor50]

I was finally able to cut the sample today. I just sent it over. I did confirm that the sample does exhibit the same issue when played on the fire tv box with the Mezzmo app.
