Web transcoding failing - h264 and mpeg2

For the h264, the web player says “Remux Running: 0s @” but nothing ever plays, it just spins. The log shows:

On the mpeg2, it says “Transcoder Running: 0s @” but nothing ever plays and it just spins. The log shows:

Could this be because I use comchap to put the chapters from the EDL in the file?

#2

Huh that’s a lot of streams. What does ffmpeg -hide_banner -i file.mpg show for the list of input streams?

This is the h264 one:

#4

Looks normal. I guess the chapter markers are affecting it some how. Do other recordings still transcode ok?

#5

Only things I haven’t added chapters to, which at this point is like 5 out of 100+ episodes ha.

#6

Send me a small sample file and I’ll see what’s going on.

#7

Just sent a link to [email protected]

#8

Seeing the same issue, but not sure why.

Do your converted files play in the Channels apps directly?

#9

Yup, no issues at all in Channels. If I use Plex and set it to transcode they play fine there, too.

#10

That’s cool, I hadn’t tested the Channels player with mkv files before.

#11

I tested one out before I started working on the rest, I just didn’t think to test it in the web player.

#12

The transcoder assumes files on disk are mpg, and is trying to the read the mkv as a mpg file. I’ll fix it for next build.
