Hi Dan,
yes that's it. When I was figuring out the problem I tried it with relocate
and it worked.
Yesterday I updated to latest MLT and played arround a little bit. The stop
problem
is fixed. I tested it with ardour, qjackctl and some other clients and it
worked.
I have some more issues but I have to investigate a little bit more. If I
have some more
facts I'll let you know.
One thing:
Is it possible to introduce more args in the filter_jackrack_init e.g. mlt
no, just set the properties as-needed before starting the consumer or
make changes to the service to deal with property changes.
properties object as args or something like this.
The idea is to be able to set more option than one. For example if I use
jack with kdenlive the name
kdenlive instead of mlt would be more obvious.
Which params should be settable. This can be discussed.
What do you think?
no
mlt_filter filter_jackrack_init( mlt_profile profile, mlt_service_type type,
const char *id, char *arg ) // multi args - to be able to set e.g. name
{
mlt_filter this = mlt_filter_new( );
if ( this != NULL )
{
char name[14];
snprintf( name, sizeof( name ), mlt%d, getpid() );
jack_client_t *jack_client = jack_client_open( name, JackNullOption, NULL );
if ( jack_client )
Thanks.

I noticed that when qtractor is running, I do not have this problem!
It seems when qtractor detects a stopped condition it calls
jack_transport_locate() or _reposition(). I did most of my testing
previously with qtractor running even when using another transport
client such as qjackctl. I hope it is not too much trouble for you to
update your MLT...

fix jack-stopped event with some JACK clients
It appears that JackTransportStopped is not received in
JackSyncCallback
unless the client that calls jack_transport_stop() also calls
jack_transport_locate().

Re: [Mlt-devel] Request for a tutorial on melted
Thank you dan for giving the details. Now i can see were i want to go. as suggested i already tried streaming files via icecast using melt which was described in FAQ under section streaming. I will look into the documentation of melt and understand the inner details of how it works so that i can figure out an a way to use it for my purpose. Also i will try to post my experiences only if the mailing-list is ok with it.

That is especially true for the clients that control melted. So, here is a tutorial on the protocol, MVCP, which you will need to do things where the clients fall short: http://www.mltframework.org/twiki/bin/view/MLT/Testing As far as being able to setup sources and outputs (called a unit in MVCP), you will need to know a bit about MLT in general. Sorry, there is a lot to figure out. Keep in mind that you can do what you describe with melted, but it was made primarily for playing from file sources and output through a SDI card. See the FAQ for examples of how to configure devices as sources and streaming outputs. You are strongly encouraged to get it working through melt before trying to make it work through melted. I am not available to provide much more assistance at this time - partly because I am putting much effort into a new client that will make this all much easier, but that is still months away for something that will help you.

If any such documentation is available please let me know. I tried to go through the documentation section of the site and found it to be long and took some time to understand how mlt works. I assume that i can feed melted with any source like webcam, handycam through DV port or through tv tuner card using composite, play a file and on the other end i can receive the same content in a player like vlc or in the browser. I am looking for such a solution. I will be very thankful for any help. Regards, Bhuvan -- Better than sec? Nothing is better than sec when it comes to monitoring Big Data applications.
