thanks for your information.
which encoder you used to make the 264 file? x.264?
please give me more details.
do we have to make the command line more specific, such as './ffplay -x 352
-y 288 test.264' in order to control the display perfprmance?
by the way, I have compiled the whole ffmpeg project using the fixed
ffplay.c in SVN source tree, but still I couldn't play the yuv file. errors
are as follows:
picture size invalid (0x0)
[rawvideo at 0x8376db0]Could not find codec parameters( Video: rawvideo,
test.yuv: could not find codec parameters
the comman line I use is : ./ffplay -f rawvideo -x 176 -y 144 test.yuv
have you ever tried the rawvideo file?
