[Cdrdao-devel] read-cd progress rewind

[Manuel C. <ll...@er...>]

Hi all,

I have tried to debug why when I extract an _audio_ cd, I see the 
progress jumping up and down.

after modifing dao/CdrDriver.cc line 4026:

     long totalTrackLen = audioReadTrackInfo_[audioReadActTrack_ + 
1].start -
                          audioReadTrackInfo_[audioReadActTrack_ ].start;
     long progress = startLba - audioReadTrackInfo_[audioReadActTrack_ 
].start;
     long totalProgress;

cout << "actualTrackProgress: " << progress << endl;

which is the same "progress" calculation that is sent to the gui.

The command line is: cdrdao read-cd --read-raw --device 0,0,0 --driver 
generic-mmc:0x0 --paranoia-mode 3 --datafile ./foo.bin ./foo.toc

and the results are:
...

PQ sub-channel reading (audio track) is supported, data format is HEX.
Raw P-W sub-channel reading (audio track) is supported.
Cooked R-W sub-channel reading (audio track) is supported.
Copying audio tracks 1-10: start 00:00:00, length 34:31:23 to "./foo.bin"...

actualTrackProgress: 134
actualTrackProgress: 160
actualTrackProgress: 186
actualTrackProgress: 212
actualTrackProgress: 195
actualTrackProgress: 221
actualTrackProgress: 247
actualTrackProgress: 273
actualTrackProgress: 299
actualTrackProgress: 325

As you can see, the progress goes up and down, that causes the progress 
bar to jump.

How can I further debug this problem?
