Downloading MPEG-2 High-1440@HL and Scalable bitstreams
Hi, everyone!
I have encoded my own implementation of MPEG-2 standard wich has to support all levels and profiles (althought maybe not at full fps for high profiles) and I can't find anywhere test sequences for that profiles. I have searched at FTP's, newsgroups, Berkeley University, and sites related with MPEG2 and had no luck. I know part 4 in the standard is all about test conformance, and says something about the name of test bitstreams, but no lead to the site where I may download them. Could somebody help me with an URL with HP@HL, High-1440@HL and some Scalable profile test sequences, please? Thank you in advance! |

You can upsize any input and encode using i.e. libavcodec/FFMPEG. (I'm not sure if they can encode HP@HL though.)

Hu? You're programming a decoder and don't know about avisynth?

hahaha
Yes, I know it and not only use it at home when ripping, but also at work to resize videos; the problem is that I have to compress the output of avisynth into MPEG2 throught a VWF codec using VirtualDub, for example, and I think is easier to do it directly throught TMPEGEnc. Furthermore, I don't know any VWF MPEG2 encoder, and I don't feel confident using ffdshow's as I got crashes when encoding using libavcodec in MPEG4... |

To anyone interested, I donwloaded one High-1440@ML and some other multi-packet transport streams at ftp://mpeg.cablelabs.com/pub/mpeg/Tektronix/
Now, there are only two more sequences to catch up: some scalable SNR and some High-1440@HL... PD: Fixed the link Last edited by Magno; 12th April 2005 at 09:20. |
