mp4 recording won't play

[sub]

There is some logic in the web application that assumes mp4 files can be played natively in the web app, which was a pretty safe bet at the time it was implemented this way. Because of this, it doesn't attempt to transcode mp4 files for playback in the web app.

Also, the web player for my Windows server will play the .mp4 file but only the audio plays. There is no video.

What type of video is it? (ie, H264...or something non-web-friendly)

That would mean there is a difference in how linux and Windows are detecting a missing ts file, since the other error was file not found. Some transcoding would likely be going on to since VCR58 uses OTA ATSC broadcast which doesn't have browser compatible audio.

Honestly @VCR58 sticking with my recommendation to keep two files is the best choice if you really must have web browser capability. Second best is to transcode to mp4 in post processing in h264/aac.

I'm pretty sure AC3 is supported in some browsers. MPEG2 video is not.

I'm OK with not using the web client, it was mostly just for troubleshooting. My main concern is that The mp4 cannot be played by the Roku app when the app is pointing to my Linux server. But the mp4 can be played by the Roku app when pointing to my Windows server.

If you've got a script which is remuxing to mp4, and deleting the .ts file. You could try using NScripHelper to call recording.rename, passing in the "from" and "to" parameters with the filenames.

It wont get it playing in the web app, but it will mean the NextPVR database knows the filename of your recording.

Cool, just tested and sure enough MS Edge did AC3, even more reason for custom profiles.

Does NScripthelper work with Linux? I have never used it before.

Yes, though you may have to do a forum search. (I think users may have had to add a text file or something - can't remember the details)

Checked the code, and you should be able to run something like:

Code:

dotnet NScriptHelper.dll -rename /some/source.ts /some/source.mp4

Some notes on NScripthelper,

1. with the deb install dotnet is not in the path so it is

/opt/dotnet/dotnet /opt/nextpvr/system/NScriptHelper.dll

2. sub's mentioned that mp4's need to be transcoded for the web player so you will have to modify your post processing to transcode.

3. sub includes NScriptHelper.deps.json in 5.1.1 so you don't need a text file for linux. What is missing now is the runtime json file for the new Windows exe.
