I made a producer that might change it's frame metadata in the middle
of the run, everything, image dimensions, audio samples, might change.
I produce the frame objects with the right data inserted in them but
at least SDL doesn't change itself to adjust to the new size.
I'd like to know if this
Hi. Still working on my shared memory module.
The module worked nicely with the sdl consumer, but had some issues when I
tried to pass the frames to an avformat consumer.
First it was throwing a "bitrate tolerance too low for bitrate" error, and
debugging that, I got to this change:

OK, a preliminary version of my module is functional. It's way away
from production grade:
* the producer segfaults on exit
* if the producer dies while holding the lock, the whole thing freezes
* if the consumer restarts, the running producer(s)'s reference to
shared memory will become invalid

I was just thinking it might be nice to normalize input. Anyways

ah, I hadn't see
I don't exactly know why, but the segfault disappeared. Now I'm back
to the speed problem. If I run this, the "current position" counter in
melt stays put in 0
$ melt -producer avformat:bm.mp4 -consumer posixshm
but if I run it with the -debug flag, I get this:
[producer avformat] bm.mp4 0

I'm getting a segfault upon calling mlt_frame_close after my consumer loop,
the code is below, and it's really simple, it just gets the frame with
rt_frame, and passes it to output. Output gets the image with
mlt_frame_get_image and copies it over to shared memory. The segfault
happens in the line

I see, but I'm the function called mlt_image_format_name in
framework/mlt_frame.c does format_enum >> name translatio
Thanks for the answer

I see there's ways of getting format name, such as "yuv422p", but I
see no way of converting that into the mlt_image_yuv422 symbol. Is it
impossible? Do I need to compare strings and do some kind of if chain?

I'm wanting to make a new module, a very simple producer-consumer
through unix sockets, and I don't know how to get started.
How do I get it to be available to programs like melt and melted? I
see there's a factory.c file in every module directory, which calls
the mlt*_registrer_* functions, but I
I just confirmed that moving the eof=loop to before the png, it works if
-consumer sdl but not if -consumer xml, can this be done?

I'm trying to generate an infinitely looping clip to XML from an image or
color, and failing. if no in/out parameters are set, the video defaults to
14999 frames long, and indeed it stops after that long even if eof=loop.
Here's my command line:
$ melt test/images/SMPTE_Color_Bars.png eof=loop -fi
