[Ffmpeg-devel] Check result of get_buffer() - patch attached

[Ronen Mizrahi]

Hi,

There seem to be many places where get_buffer() is invoked and the 
return value is not checked for errors. One particular place that was 
causing issues for me is the get_buffer() invocation in 
av_open_input_file(). When I was opening HTTP URLs that were no longer 
valid get_buffer() was failing yet it was not detected. Please see 
attached a patch that is fixing this particular issue. Later on, time 
permitting, I will try and submit patches for all the locations where 
get_buffer() is used and the return value is not checked for errors.

Thank you,

Ronen Mizrahi
