Hello,
I wish to use ffmpeg to play MJPEG stream on a video viewer.
Wanted to know if there is any limit on resolution supported ?
Is there any MAX Width and MAX Height
For my application max requirement is to decode "4000 x 3000". Looks like it is
supported.
Looking at the mjpeg decoder source file in ffmpeg
library(ffmpeg-1.0/libavcodec/mjpegdec.c)
A function named "av_image_check_size" is used to check image size. Following
is the code snippet :
-----------------------xx----------
int av_image_check_size(...)
{
...
if ((int)w>0 && (int)h>0 && (w+128)*(uint64_t)(h+128) < INT_MAX/8)
return 0;
...
}
Note: This function is defined in "libavutil/imgutils.c" file.
----------------------xx-----------
INT_MAX = 2,14,74,83,647
This means resolution of little more than "16,000 x 16,000" is supported. Just
considered 1:1 ratio here.
Is my understanding correct ?
Thank You,
Snehal
