Now externremux.sh will use mencoder, ogg or cat for remuxing.
Would it be possible to have suppport for ffmpeg too ?
If you could provide some typical working examples for ffmpeg calls, I'd be happy to add ffmpeg to externremux.sh. The ffmpeg calls themselves are enough. I don't expect you to properly include ffmpeg in the current externremux.sh ;)
If you need some help to setup a simple externremux.sh (without all the parameter substitution stuff) for testing, please let me know.

ffmpeg -f mpegts -i - -vn -acodec libmp3lame -ab 32000 -ar 44100 -ac 1 -f mp3 pipe:1
this works for me fine!
#!/bin/bash
echo -ne 'Content-type: video/mpeg\r\n'
echo -ne '\r\n'
ffmpeg -f mpegts -i - -vcodec mpeg4 -b 4096000 -vf scale=512:288 -acodec libmp3lame -ab 32000 -ar 44100 -ac 1 -async 50 -f mpegts pipe:1
This works fine with mpeg2 content. But how can the script be told, that it is
h264 content?
Streamdev passes the video type to externremux.sh in variable REMUX_VTYPE. The value 2 indicates mpeg2.
Or is your problem ffmpeg? I don't have much experience with it, sorry.
