I am successfully using VLC/VLM 1.1.0-git The Luggage for several
tasks involving reshaping and filtering mp2 A/V streams, but there
seems to be a feature impossible to get working.
When the select directive is used within a vlm.conf file, it seems
able to accept only single word expressions, as "audio" or "video"
directives. More complex syntaxes seems to be skipped.
For example, I have the following simple vlm.conf file:
Code: Select all
new channel1 broadcast enabled
setup channel1 input in.ts
setup channel1 output #duplicate{dst=standard{access=file,mux=ts,dst=/tmp/out.ts},select="program=3401,audio"}
control channel1 play
but ignores the program number. So, even though the program 3401 is included
in the input ts (I can correctly decode it through the vlc gui), the selected audio
is that of the first program, independently of the "program=" directive.
It seems that vlc understands the select string, but nothing happens.
The output messages are as follows:
Code: Select all
