Skipping/Stuttering on SD IPTV with 11.0.1

Hello!

I have a weird problem with my RPi4 since i updated to LE 11.0.1

I watch TV Streams via TV-Headend-Server and TV Headend Client. It worked fine with LE 10.0.4

Since 11.0.1, the 720x576@50 streams started to stutter and to skip frames. The 1280x720@50 streams work fine, so it doesn‘t seem to be a performance issue. I tested using force_turbo=1 and/or core_freq_min=500 in the config.txt though to no avail.

So, HD-Streams@50fps work fine, while SD-Streams@50fps don’t.

I turned off the deinterlace option, which didn't help. I then turned off PRIME HW Decoding and the streams played fine, without stutter. The issue must be somewhere within the HW decoding routines. I will provide a sample of the TV stream, it's always reproduceable.

Greetings, Dominique

A sample Stream is located here (plays fine with 10.0.4, skipping/stutter with 11.0.1,

HiassofT , could you take a look at this please?

good news, thanks

i will test that build and report back how it works. Thanks for your efforts!

HiassofT yes, my IPTV Streams play fine now with that build. There are no side effects to other streams or videos, all play fine. I tested HD TV streams also and my video collection (x264 and HEVC at different frame rates)

Good job on that fix.

will this fix be in 11.0.2?

Thanks. I will test that build and report back.

HiassofT

my Feedback for the nightly build: it works fine and playback of IPTV Streams is flawless.

Media plays normal (x264/x265)

Well done!
