Why calling libav* library doesn't have same quality as ffmpeg command line ?
10 mai 2016, par seaguestI am using the ffmpeg 3 to do the video format conversion, it works fine when I use the command line mode, but when I call the libav* library, I get a audio quality loss problem (there is a lot of noises in the audio).
Here are the two files :
mv.webm - original file
mv2.mp4 converted with libarary , a lot of noisesHere is the probe information for the mv.webm :

Why the command line mode and use libav* library mode with same setting, but have different output ?
What should I do to call libav* library to get lossless video conversion ? -
FFMPEG not enough data (x y), trying to decode anyway
7 juin 2016, par Forest J. HandfordI’m trying to make videos of Direct3D games using a C# app. For non-Direct3D games I stream images from Graphics.CopyFromScreen which works. When I copy the screen from Direct3D and stream it to FFMPEG I get :
[bmp @ 00000276b0b9c280] not enough data (5070 < 129654), trying to
decode anywayAn MP4 file is created, but it is always 0 bytes.
To get screenshots from Direct3D, I am using Justin Stenning’s Direct3DHook. This produces images MUCH bigger than when I get images from Graphics.CopyFromScreen (8 MB vs 136 KB). I’ve tried increasing the buffer (-bufsize) but the number on the left of the error is not impacted.
I’ve tried resizing the image to 1/6th the original. That reduces the number on the right, but does not eliminate it. Even when the number on the right is close to what I have for Graphics.CopyFromScreen I get an error. Here is a sample of the current code :

}When I search the internet for the error all I get is the FFMPEG source code, which has not proven to be illuminating. I have been able to save the image directly to disk, which makes me feel like it is not an issue with disposing the data. I have also tried only grabbing one frame, but that produces the same error, which suggests to me it is not a threading issue.

Any ideas would be greatly appreciated. My current workaround is to save the files to the HDD and compile the video after gameplay, but it’s a far less performant option. Thank you !
