Re: [LAD] [ANN] jack-file 1.0
Hi Dan, Nice idea, it is is essentially a command line audio file sequencer right? (That syncs up to JACK transport). I'll checkout the code when I get some time, just to see how you've designed it... :) -Harry On Mon, Jul 4, 2011 at 12:45 PM, Dan Muresan wrote: > Hi, jack-file 1.0 is available on github: > > http://danmbox.github.com/jack-file/ > > It contains file2jack, a Jack transport-centric audio player that maps > files onto the (optionally periodic) transport timeline.

Hi Dan,
A couple of immediate issues:
1) make fails when it can't find help2man. it then complains (twice)
file2jack isn't found either (an ls after the fact shows it is):
cc -Os -g -Wall -Wextra -pipe -std=c99 -D_REENTRANT -ljack
-lpthread -lrt -lsndfile -lm -lpthread -lrt csrc/jacktransportloop.c
-o jacktransportloop
mkdir man
help2man -N -o man/file2jack.1 /home/sirrom/SRC/jack-file/file2jack ||
{ file2jack --help || :; file2jack --version || :; false; }
/bin/sh: help2man: command not found
/bin/sh: file2jack: command not found
/bin/sh: file2jack: command not found
make: *** [man/file2jack.1] Error 1
2) floating point exception when command issued without options:
Core was generated by `./file2jack'.
Program terminated with signal 8, Arithmetic exception.
#0 compute_frames (argc=, argv=) at csrc/file2jack.c:659
659 jbuf_len = ((jbuf_len - 1) / denom + 1) * denom;

Re: [LAD] [ANN] jack-file 1.0
Hi, and thanks for checking out my project. > 1) make fails when it can't find help2man. it then complains (twice) > file2jack isn't found either (an ls after the fact shows it is): Well, help2man is listed as a build dependency, and I don't think it's proper style to verify dependencies in the makefile. In ./configure, yes -- but I'm not using one. > 2) floating point exception when command issued without options: That, indeed, is not nice. It happened because I left the arg parsing routine open till the last moment. Fixed in git. To tell the whole story, I was hoping eventually to make both file2jack and jacktransportloop infrastructure-apps that could be controlled via stdin. So file2jack could start with nothing, and accept commands to add/remove files to the transport timeline. Plus there would be a tkJackTransport app that actually scrolls the timeline (unlike gjacktransport, which is unhelpful when the transport overshoots the display limit) and has a loop checkbox and two time entries. I couldn't fit this in the first release. If anybody wants to help... But otherwise -- did it work for you when you passed proper args? -- Dan ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev

Admittedly, I didn't quite get it at first because I'd only really skimmed the description. I was mostly wanting to look at the code as I'm interested in trying to get a better grasp how data is passed between threads when using JACK. I find the code somewhat difficult to follow.

I hope file2jack will keep it simple. Are you planning to add other decoder backends? If file2jack could play sound from .avi, .mov and .mp3s, etc along to jack-transport, I could finally retire the kludgy jplay2 http://rg42.org/oss/jplay2/ player. jacktransportloop is a very nifty tool; but it's not very accurate: Calling jack_transport_locate() will make jackd go back to the "Starting" state: http://jackaudio.org/files/docs/html/transport-design.html Just launch some other jack-transport apps (e.g. ardour with a few tracks) and you'll notice a short hiccup. One alternative would be to just wrap the timecode internally in file2jack (fold back, modulo) and keep going.. what do you think? > Plus there would be a tkJackTransport app that actually scrolls the > timeline (unlike gjacktransport, which is unhelpful when the transport > overshoots the display limit) and has a loop checkbox and two time > entries.

You can tell gjacktransport the start/end position of its timeline on startup: gjacktransport 10 100.2 # from 10 seconds -> 100.2 seconds and one can also write a custom .rc file which can include N<99 predefined ranges and load it with gjacktransport -l on startup e.g. http://gjacktransport.git.sourceforge.net/git/gitweb.cgi?p=gjacktransport/gjacktransport;a=blob;f=src/gjacktransportrc It would not be too hard to add an OSC interface so that one can update those from an external app. But depending on your goals (loop checkbox, paging, maybe even display audio-chunk position, etc) you may indeed want a custom application. > But otherwise -- did it work for you when you passed proper args yes. An *option* to specify JACK ports to auto-connect would be nice. and I'd like to file a feature request for libSRC integration instead of calling 'sox'.

Before I answer anything else, have you noticed the comments to that order in README.txt (and in the announcement)? file2jack does exactly this (it computes what to send at every time point, and it can behave like a periodic function). It does not move the transport at all. -- Dan ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev

That was not obvious to me at first; but I understood it just after sending the previous email from `file2jack --help` "LOOP" option. > It does not move the transport at all. > > -- Dan Thanks for shedding some more light on this matter. keep up the good work. ciao, robin ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev

I will, of course accept contributions to the documentation, as well as the code. Though to be honest the fact that file2jack does not move the transport is in the first paragraph of README.txt (and the webpage) :) -- Dan ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev
