Displaying Green Color video

[neelima]

We are currently working on this Android 3D Animation App. We need to do video encoding as well as audio syncup on encoded video. We are using ffmpeg tool for this video encoding.

Sequential Steps taken by us:-
Step 1. We are taking screenshots of the identified images for video encoding exercise.
Step 2. Saving them in SDCard.
Step 3. Then we are calling the avcodec_init method and subsequently avcodec_register_all method.
Step 4. Then we are reading the SDCard images and allocating them to memory in FFmpeg.
Step 5. Then we are calling rgb2yuv method.

Then we are getting output source as green color video. Please help us where we are missing. Whether this issue is in rgb2yuv method.

Many Thanks in Advance.

I asked you in ticket #1772 to add some information and to test current git head.
You did not answer, instead you are opening new tickets that do not contain enough information to reproduce your problem.

We have attached vidapi.c file. We request you to please review our code in encodeVideo() method. Thanks in advance.

I fear there is a misunderstanding:
This forum is for bugs in FFmpeg, not for bugs in software using FFmpeg (and not for FFmpeg support).
Please read https://ffmpeg.org/contact.html to find out about support mailing lists.

Just as a hint in case it helps: a all-green frame means a YUV frame probably had its all-0 initialization value. So sws_scale probably never writes into the destination frame.
But I see no real reason to believe this is a bug in FFmpeg, if you do please provide an absolutely minimal test-case that proves it.
I'm afraid we can't help you debugging your code, we don't have enough resources for that.
