[Ffmpeg-devel] [Ffmpeg-user] Capture a frame in a JPEG ffile:continued

[Vlad GURDIGA]

Hello,

I decided to give you some more information so you could more easy
give me a piece of advice.

As I said before, until now I only managed to capture 10 frames to 10
files in PPM format, as it was in the example enclosed to the tutorial
(http://www.inb.uni-luebeck.de/~boehme/libavcodec_update.html). I
guess it only needs a slight modification to save the frames in JPEG
files, but I cannot figure it out because I did not get so deep into
the theory. I have attached my working C# code, hope will be
comprehensible for C/C++ developers too. I could not insert it in line
because lines are too long. A note on code: VideoUtils is a small
library that imports the functions I use and implements structures,
constants and enumeration types. All the "action" is in the Create()
method.
