Hello All,
I am using a little older version of FFMPEG. I try to play a file with FFMPEG
which is only 1 MB. Now when I try to play that file, it first tries to get the
stream info and reaches the end of the file while extracting the stream info.
This results in no audio/video during playback and when I seek to any earlier
location, it plays well. There is a check for MAX_READ_SIZE in
av_find_stream_info in libavformat/utils.c
if (read_size >= MAX_READ_SIZE) {
ret = count;
break;
}
The MAX_READ_SIZE is defined as 5000000 which is almost 5 times the file size I
m trying to play. If I reduce this size by 10 times to just 500000, I am
successfully able to play the file.
Can you please help me understand why this file size has been kept as around 5
MB and what should be the optimum size so that we can handle files like in my
case? If I look at the newer versions of ffmpeg, this macro and the check has
been removed.
Regards
Ankit Singhal
