On 700D there are 16 used resources for TTL_ResLock, I did some experiments and seems using only 5 of them is enough to get valid lossless compression in both RAW video and Silent picture:

Code Select Expand

    if (is_camera("700D", "*") || is_camera("650D", "*") || is_camera("EOSM", "*") || is_camera("100D", "*"))
    {
        uint32_t resources[] = {
            0x00000 | edmac_channel_to_index(edmac_write_chan),
            0x10000 | edmac_channel_to_index(edmac_read_chan),
            //0x20005,//no effect
            //0x20016,//no effect
            //0x30002,//no effect
            //0x50034,//no effect
            //0x5002d,//no effect
            0x50010,//affect silent pic
            0x90001,//affect silent pic + raw video
            //0x90000,//no effect
            0xa0000,//camera lock up without it
            //0x160000,//no effect
            //0x260000,//no effect
            //0x260001,//no effect
            //0x260002,//no effect
            //0x260003,//no effect
        };

Also, if we want to throw out Silent picture, only using 4 resources would work fine for RAW video which are:

Code Select Expand

0x00000 | edmac_channel_to_index(edmac_write_chan),
0x10000 | edmac_channel_to_index(edmac_read_chan),
0x90001,
0xa0000,

if we want to make Silent picture works it become:

Code Select Expand

0x00000 | edmac_channel_to_index(edmac_write_chan),
0x10000 | edmac_channel_to_index(edmac_read_chan),
0x50010, ---> Added this
0x90001,
0xa0000,

-Why I am mentioning this?

I have hope that DIGIC 4 models would have similar thing, by looking back at DIGIC 4 experiments, we can see notes about there are conflicts among some TTL_ResLock resources and LiveView:
Greg's experiment on 500D, a1ex's experiment on 60D

-TTL_ResLock resources from logs:

-500D from Greg
-7D from nikfreak
-5D2 from reddeercity
-550D from reddeercity
-50D from aprofiti

So the shared resources among DIGIC 4:

1)    10002 (read channel 0xa)
2)        3 (write channel 0x3)
3)        4 (write channel 0x4)
4)    30000 (read connection 0x0)
5)    20005 (write connection 0x5)
6)    20016 (write connection 0x16)
7)    50003 (?)
8)    5000d (?)

-Comparing DIGIC 4 resources to 700D:

For first two, resources are for read and write EDMAC channels, we shouldn't worry about them.
For 0xa0000, it's shared among all models DIGIC 4 and DIGIC 5, this seems the most important one, camera locks up without it on 700D
Last one for 700D it's 0x90001, I don't know which one is equivalent on DIGIC 4, could be 0x80000 or 0x90000? , but 0x80000 was conflicting with LiveView.

For silent pic, 0x50010 was required on 700D, could be 0x5001a on DIGIC 4, or 0x5000X ? but 0x5001a was conflicting with LiveView, Greg's notes

-Of course I could be wrong, maybe other resources are required too on DIGIC 4, well, maybe not all of them are required, knowing this thing may make things easier.

-I can't test these, no DIGIC 4 models around me, but might provide some tests (not in near future).
-I read that the newer DIGIC 4 models like 60D, 600D and 1100D are the easiest D4 models to start digging into it because of their similarities to DIGIC 5.
-Probably I need to check what the minimum required resources on 100D (could be same as 700D) and 5D3 and see if the theory applies there.

The above 2 pieces or log file , i think is needed to get lossless compression working on 5D2
the below piece of log file is related to all D4 cams but i suspect somthing is needed from the above
log file , as previous lossless compression test (silent picture) always lockup during the saving routines. Like the its not unlocking or locking the (ProcessTwoInTwoOutJpegPath) that the D4 version
of lossless , plus I think D5 cam use 4 in & 4 out streams maybe just the 5D3 , the D4 use 2 in & 2 out . In the end there some missing resources or the code structure is wrong for d4 (wouldn't be the first time i had to change so D5 code to work in D4 cams
