Repair TS for Chromecast
« am: März 11, 2021, 18:42:32 »
Hello All,
I'm evaluating TS-Doctor 3.1.8 to see if it can resolve a long standing issue I've had playing MPEG2 files on Chromecast.  The files are ATSC broadcasts recorded by MythTV with a SiliconDust HDHomeRun, streamed through Plex to a Chromecast.  The vast majority of files work just fine.  However, occasionally, one of the recordings will consistently cause the Chromecast to reboot at some point in the recording.  I do not see errors in Plex when this happens.

I opened an example file in TS-Doctor 3.1 then saved to a new file in an attempt to fix the video, but I do not see an improvement.  The "Result of the process" screen displays 5 warnings and 3 errors.  I'm not sure if these are found and corrected, or just found.  Any advice?  Am I using the program correctly?

Here is the log:

Hi, so far as I can see there were reception problem during the recording, creating errors and missing packets. TS-Doctor can not perform miracles and bring back missing data but can try to make the scars less visible. Most mediaplayers have not problem with little scars in TS recordings because it is pretty common to have some errors (reception interference) in transport streams from time to time.

Try to use Tools/Expert tools/"TS Packet Timing" on the fixed file and please post a screenshot of the result, to see if the important timers are OK.

Video PTS and PCR looking good. No jumps, no problems.

Is current version of Plex in use and the Chromcast device has the current firmware?
Check if Plex is transcoding the file and try to disable it.

Yes, Plex is fully updated and the Chromecast is running the latest firmware.

I disabled transcoding in Plex, but all my broadcast recordings would not play, with the following errors in the Plex console:
[Chromecast] [PDE] Unable to play item; This server is not powerful enough to convert video.
[Chromecast] [MDE] Unable to play; server unable to transcode video
[Chromecast] [MDE] Soft subtitles failed; Closed captioning
[Chromecast] [MDE] Invalid profile property; protocol: undefined !== hls
[Chromecast] [MDE] Unable to validate protocol; re-analyze the media if possible
[Chromecast] [MDE] Starting analysis of 720 (mpegts, mpeg2video, ac3, 4, main)

Also, I tried Play Original Quality in the Plex android app, but the Plex logs show that it is still being transcoded.

Any further thoughts?  I read that demuxing and remuxing might fix.  Any truth to that?

Could help but there is also a good chance to introduce new problems like loosing the lipsync.
