Component: internal MyThTV player
What steps will reproduce the bug?
Select a video (under "Media Library/Watch Videos") and play the video. Playback works fine, but when seeking (using the "Right Arrow" key), the video freezes, "Searching" appears as MythTV on screen element and after a while (ca. 60 secs) MythTV crashes and restarts.
This happens with most of my own ffmpeg-encoded videos (*.avi, *.mkv, *mp4).
The problem is, all video files work flawlessly in previous MythTV versions and other players (e.g. VLC) since years.
As workaround I use now the setting in the MythTV-Frontend "Default Player: vlc").
My coding steps:
mythtranscode --chanid $CHANID --starttime $STARTTIMEUTC --honorcutlist --mpeg2 -o "video.cutted.mpg"
ffmpeg -y -threads 0 -i "video.cutted.mpg" -codec:v libx264 -preset slow -filter:v yadif,scale=1024:576,setsar=1:1 -sws_flags lanczos -b:v 1000k -pass 1 -map 0:v -codec:a copy -map 0:1 -f mp4 "$TITLE_FRIENDLY_FILE.pass1.mp4" &>"ffmpeg.pass1.txt"
ffmpeg -y -threads 0 -i "video.cutted.mpg" -codec:v libx264 -preset slow -filter:v yadif,scale=1024:576,setsar=1:1 -sws_flags lanczos -b:v 1000k -pass 2 -map 0:v -codec:a copy -map 0:1 -f mp4 "$TITLE_FRIENDLY_FILE.pass2.mp4" &>"ffmpeg.pass2.txt"
How often does it reproduce? Is there a required condition?
With problem videos it occurs 100 % reproducible.
What is the expected behaviour?
Playback and seeking in videos should work flawlessly, as in previous MythTV versions.
What do you see instead?
Video freezes and “Searching” is displayed as a MythTV element on the screen above the full-screen video playback.
Additional information
The problem occurs in my different settings (Ubuntu 24.04.3 LTS and Linux Mint 22). I think the problem is in the internal MythTV player. My video files are correct.
