Encoding/container for mpeg-ts audio and MINIDLNA compatibility

Added by william darcey almost 4 years ago

I'm recording from uk freeview. I can successfully watch tv programmes using minidlna, be they recorded using passthru, matroska or various ffmpeg transcode via spawn stream option.

I can't however find a successful combination of outputs for a radio channel received via same freeview uk adapter. The files play back fine locally. But minidlna cannot parse them and so does not present them to dlna clients.

Can anyone suggest a transcode that produces a file recognizable by minidlna?

Many thanks.

The passthru recording details:

RE: Encoding/container for mpeg-ts audio and MINIDLNA compatibility - Added by william darcey almost 4 years ago

I managed to produce a file, recognised by both minidlna and my radio, by invoking the following ffmpeg command in a stream profile and outputting a file with .mp3 extension in the recording profile. Then a post record script to add ID3 tags. Works for the radio channel concerned but I suspect other freeview radio channels have different stream layouts.

#!/bin/sh
ffmpeg \
-i pipe:0 \
-map 0:a:0 \
-c:a mp3 \
-f mp3 pipe:1
    (1-1/1)
