Hi to all,
I have some serious trouble with RTP and Liquidsoap. My platform is an
iMX6Solo embedded board with Yocto based Linux(with 3.14.28 kernel
version). By default, there are not available Ocaml compilers for this
platform, but i have solved the problem using a external ARM compiler(an
Orange PI board), installing Liquidsoap in Orange first through OPAM with
all plugins available, then manually coping binaries and libraries on iMX6
board. With HTTP streams, MP3 playlist and so on Liquidsoap run very fine
on my board, but when i try to encode or decode RTP streams i have some
trouble:
On stream decoding, Liquidsoap simply not recognize the multicast stream,
causing the source to failure(see logs), while in stream encoding Gstreamer
reports an error on "appsrc"(see logs).
On original platform(orange pi), the same Liquidsoap working perfectly, in
RTP too, both encoding and decoding.
