identify,it is mpeg2,but mplayer use ffmpeg12vdpau to decode video stream :em06

because it is a m2ts file,so video stream usually is encode by mpeg2 ,not h264

"m2ts" is a kind of container like mkv/avi/ts/tp and so on which can also package H.264/VC-1 video stream inside itself.

you're right

but this m2ts file i download is mpeg2

i recheck it by mediainfo,i am right

it's mpeg2

but,why it called ffmpeg12vdpau?

I don't think mpeg1 need hardware acceleration. It's mainly used in VCD which can be decoded very well even by a Pentium3 processor.

And then, most of modern NV cards support mpeg1 acceleration in a bad way - don't support VLD-level hardware acceleration. That might lead many errors when decoding.

i think so

maybe decode mpeg1 and mpeg2 use the same way?

so they named it ffmpeg12vdpau

English is very important for any IT technician because IT technology lies in the hands of Americans.

My Card...only IDCT is supported

D V DT mpeg1video_vdpau MPEG-1 video (VDPAU acceleration)
D V DT mpegvideo_vdpau MPEG-1/2 video (VDPAU acceleration)

MPEG1&2 encoding method are similar, but requires different FPS&resolution.

When decoding, they think these two are similar.= =

My ATI HD card only support MPEG12 IDCT...No VLD
but the IDCT can not give the processor any pressure..
