Bugreport - channel switch

Help and Support
1

Hi all,

When switching from mpeg2 tvheadend tv source to mpeg4 the image freezes on mpeg2 source and audio plays (badly - “buffering” every few sec.) and it does not respond to any remote key so the only “fix” is reboot
If that does not happen then the sad face happens and it reboots.

This happens no matter if you are in full screen or not.

here’s the log from when it gets stuck

Have you purchased and installed the mpeg2 codec yet?

3

mpeg2 works (no lic), picture is there,all good but when you change channel to mpeg4 channel you got stuck with what I’ve said in my post.

By looking at the logs:
22:22:13 8419.419922 T:1706030064 NOTICE: 1Channel: Service: Playback started
so, we have playback

22:22:20 8426.783203 T:1464853488 NOTICE: Creating video codec with codec id: 2
22:22:20 8426.783203 T:1464853488 WARNING: CMMALVideo::Open Codec mmal-mpeg2 is not supported
22:22:20 8426.784180 T:1464853488 NOTICE: CDVDVideoCodecFFmpeg::Open() Using codec: MPEG-2 video

then we have a channel change event

22:22:35 8441.743164 T:1464853488 NOTICE: PVRManager - PerformChannelSwitch - switched to channel ‘Doma TV’
22:22:35 8441.744141 T:1464853488 NOTICE: Creating Demuxer

I’ve also tried to disable mmal HW accel and do the same thing, ended up with sad face.

It is not a confirmed bug if you have not made every effort to resolve the issue by using all tools available.

If you haven’t noticed, I’m giving you a hint, Sir.

5

Yes, I believe without a license you will have problems changing between different stream types.

I think this is resolved in the upcoming Kodi Krypton but it may be worth buying the license

6

Correct. Jarvis doesn’t handle a stream changing between hardware and software decode without manually stopping.
Get the MPEG-2 codec licence or update to a Krypton test build (or wait for Krypton to become stable pretty soon).
