Question / Help How to? ffmpeg UDP MPEG-TS

[Paul Anderegg]

I cannot get anything on my Teradek decoder, when using the "start recording" and the options setting set for URL (udp://ip:port) and "mpegts". Can someone please advise what other settings must be configured to enable MPEG-TS out of my system. Is the ffmpeg encoder pointing to a plug in I have not installed? New to this, seeking assistance, thanks! :-)

You need to post the specs/compatible video info of the Teradeck.

It's a Cube, it is set for MPEG-TS UDP port xxxx, it is a known and working Teradek we use for sending MPEG-TS streams from Sony and JVC broadcast cameras. I can send streams to YouTube and such, no issue, but this "record" settings thing for MPEG-TS just isn't being seen by my decoder.

This is what I am trying to do on the OBS screen.

Hmm...
1. Change the Audio Encoder in OBS to AAC (or change the Teradek to mp2 audio). That's a mismatch.
2. Make sure that OBs is set to 59.94 for it's fps (Settings->Video).
3. What Codecs does the TeraDek support on ingest? MPEG2, or MPEG4/H.264/x.264 or something else?

 

[Paul Anderegg]

Changed the Teradek to mp2 audio, OBS was already at 59.94, and I am not sure what codecs Teradek supports for MPEG-TS, I believe it is the baseline flavor of MPEG2 everything. It can do h264 for other forms of streaming though.

Still no dice. :-(

Do I need to install ffmpeg dmg?

Hmm according to http://teradek.com/collections/decoder/products/cube_305?variant=1151427421#techSpecs
(The video specs sub part), it would seem that it only supports h.264, not MPEG2. You have OBS set to output MPEG2 video.

 

[Paul Anderegg]

Hmm, I see that in the specs. I thought MPEG-TS was MPEG2? Any clue what output I would select to shoot a signal at the Teradek using the Teradek settings on the above picture?

MPEG2TS is a container. It can be used to house MPEG2 video, or other codecs (including -but not limited- H.264).

I would try setting the OBS Video Encoder to h.264 and see what happens.

Also, I would set the Teradek and OBS both to AAC for the Audio.

 

[Paul Anderegg]

The OBS "mpegts" container can only house mpeg2 video and mpeg2 audio...the selector will not show any other options...does this mean OBS is incapable of sending an h264 mpeg-ts UDP stream to the Teradek?
