I have fix some Pbs with my virtal_VCR, by using the last dvgrab version 0.7 with a patch that can output files for playdv (last version). The movie is good (I can finally reconize the dog). But playdv crash at the end of the movie (segmentation fault), here is the error output : ** CRITICAL **: file bitstream.h: line 155 (bitstream_unget): assertion `(num_bits <= 32) && (num_bits >0) && (!(data & (~mask)))' failed. Since xdv0.1 does not correctly decode my isochrone flow, I will try to build a direct line movie player which will use dvgrab's --dv algorithms option and the libdv codecs. Currently, I have a ROM for IEEE 1394 boards. I have a small program that listen to FCP commands and try to respond like a VCR does. (Probably soon avaible) But I do not support yet all commands described in the AV/C Tape Recorder / Player Subunit Specification. In fact, I do not now exactly what is meaning of some commands. And what are the main commands to support. --- Franck Bonin --- Andreas Micklei a écrit : > Hi, > > On Thu, May 11, 2000 at 04:11:07PM +0200, Franck > Bonin wrote: > > So I have tryed to transform my PC-linux in an > > TapeRecorderPlayer and > > today I have succeded, by re-writing the > ohci_csr_rom > > located in the ohci1394.h file. > > That is great.
