Looks like this is due to libyuv code being pulled in for converting MJPEG to ARGB. Not sure if there is any way around this if we want image capture to work on file-backed fake devices on Android.

alaoui.rda@: You initially reported this feature as missing on Linux. How important is it to you to have this work on all platforms including Android?

mheikal@: If necessary, we could consider adding an OS Switch in the code to turn off the newly added functionality on Android. I am unable to tell how "bad" an increase of 16kB is, so it is hard for me to weigh the upsides vs. downsides.

In terms of 'how bad is 16kb'. It's actually the smallest change that we alert on. Worth having a look at, but not worth spending more than a day on.

re #3:

I had to add |blob_utils.h| and |blob_utils.cc| import to every platform [1] including android otherwise the android bots were failing [2][3].

[1] https://chromium-review.googlesource.com/c/chromium/src/+/890739/16..17
[2] https://chromium-review.googlesource.com/c/chromium/src/+/890739/14..16
[3] https://ci.chromium.org/buildbot/tryserver.chromium.android/android_n5x_swarming_rel/353768

And blob_utils requires libyuv

Makes sense. With that, I would say the increase in size is expected due to the newly added functionality and mark this as WontFix.
