Sony Vaio Pro webcam does not work in most of the apps with libjpeg-turbo8-1.3.0-0ubuntu2

[Vasiliy]

I'm using Ubuntu 15.04.
The version of libjpeg-turbo8 is 1.3.0-0ubuntu2.

Expected:
A video picture from the webcam.

What happens instead:
The output is just a garbled picture or sometimes the green screen.

For example, cheese fails with:
libv4l2: error got 4 consecutive frame decode errors, last error: v4l-convert: libjpeg error: End Of Image

The webcam (ID 0bda:5793 Realtek Semiconductor Corp.) has MJPG as one of the formats.

Most of the apps (cheese, google-chrome, etc.) don't allow to select other format for the webcam. Thus this webcam is unusable in those applications.

This is fixed in libjpeg-turbo 1.4.

Only upgrading libjpeg-turbo to 1.4 didn't help.
I tried:
http://debomatic-amd64.debian.net/distribution#vivid/libjpeg-turbo/1.4.1-0ubuntu1
with http://debomatic-i386.debian.net/distribution#vivid/libjpeg-turbo/1.4.1-0ubuntu1

I'll try to boot arch live, because in the chromium link they say they solved the problem.

Hi, I found a workaround for this bug on my SVP1321C5E.

Opening cheese gives the exact same error: libv4l2: error got 4 consecutive frame decode errors, last error: v4l-convert: libjpeg error: End Of Image.

I solved it by opening the preferences and changing the resolution for pictures and videos: default was 1280x720, I changed both of them to 640x480. I then closed Cheese and opened it again, and everything was working fine.

I haven't tested any other application (Skype, ...).

Vasiliy, thank you for reporting this and helping make Ubuntu better.

As per https://wiki.ubuntu.com/Releases, Ubuntu 15.04 reached EOL on February 4, 2016.

Given you noted in the Bug Description this is fixed in libjpeg-turbo 1.4, could you please confirm this is still the case via testing http://cdimage.ubuntu.com/daily-live/current/ and advising to the results?
