Ffmpeg renderer causes stuttering?

[user84 46]

When I direct play media, I have noticed that when the renderer is listed as "ffmpeg" my video stutters when attempting to play at any level of 1080p. If I drop to 720, the issues resolve. Most of my media lists "mediacodec" as the renderer, and I have no issues when that is the case.

How do I remedy this?

Hi there, let's look at an example. Please attach the information requested in how to report a media playback issue. Thanks!

Thanks so much for the reply. I was hoping for some general troubleshooting info before I post an example

Hi.  What is the device?  My guess would be it just isn't powerful enough for the video in question.

It's an Amazon fire stick. The server is running Windows 11 with a 9th gen i5 Intel chip.

Just for my own education, what impacts the renderer that is used?

Just a plain stick?  An older one?  That is likely the issue - just not enough CPU power.

Device hardware support (or lack thereof).

Its the newest 4k model. Confusing why it would have issues. I'll keep an eye out and see if any other media is impacted.

Factors that can reduce video encoding throughput and possibly cause buffering when direct play is available:

1. Original media bitrate
2. Original media stream corruption (playback on another 3rd party player is not a valid test to find media metadata errors)
3. Number of subtitles (many media have 25 + subtitles)
4. Other demand on the server
5. Network connections
6. Router hardware
7. Router software setup
8. Cable type
9. Ethernet switch if used
10. Wifi setup and conflicts, if used
11. TV App connectivity and security (often 3rd party incoming stream might get limited by TV software preferences for security)
    
    I probably missed something.  So which one of these might it be?  If we don't see a log, it's impossible to tell.
