Looking for 650D user input on a short test.
The audio meters were broken on the 700D and since the 650D is closely related I'd like to see if maybe it is also happening on the 650D.
The way to run the test is fairly simple. Turn on both the mlv_rec and mlv_snd modules and activate those modules. I prefer to reduce the frame to the smallest size because we're only checking for an audio issue. The first time you record an MLV clip the audio meters should work normally. What I'm interested in is what happens on the second through the forth clip. Make sure not to restart the camera between takes. Do the audio meters continue to operate normally? On the 700D the audio meters stopped working after recording the first clip. Of course more important is if sound is being recorded to the MLV file. In the case of the 700D the audio did get recorded even though the meters weren't working.
We're running an experiment with mlv_snd that might be affecting the 650D. Go to my
Bitbucket download page and get both these files:
650D_test_mlv_snd_fix.2017Oct02.650D104.zip
650D_test_stubs_fix.2017Oct02.650D104.zip
Run the same test as above and please report your results in the "
Will the real SoundDevShutDownIn please stand up" topic. My theory is that these test builds should work the same as the current nightly but I don't have access to a 650D to test my theory.
For a quick explanation of what is going on, a few cameras have the same address for two different stubs, SoundDevShutDownIn and StopASIFDMAADC. We're running a test in the crop_rec_4k branch to put things in order but we want to make sure nothing breaks on the other ML supported cameras. The 650D_test_mlv_snd_fix uses the
fix found for the 100D which calls both SoundDevShutDownIn and StopASIFDMAADC to stop the audio while the 650D_test_stubs_fix uses the
fix found for the 700D which doesn't use either of those functions so they are commented out in the stubs.S file. Note that the 650D doesn't have the StopASIFDMAADC defined.
