Memory leak in QVideoEncoder #6

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
img_convert_ctx isn't freed on close()

ffmpeg::sws_getCachedContext() tries to use an already existing context but 
fails because initVars() sets img_convert_ctx to zero. So a new context is 
allocated on every new video.

Adding the following lines to QVideoEncoder::close() (before initVars) solves 
the problem:
// free the sws-context
sws_freeContext(img_convert_ctx);

Another solution would be of course to remove the corresponding line from 
initVars()
