Bug in MP4 encoder, x264 mode

Post by kibi »

Hi, Steipal!

At first, thank's a lot for great and usefull software!

I've just found some bug in MP4 Encoder. It coudn't produce the correct result in x264 mode for some clips . But if you change the mode to MPEG4 - everything is OK.

The test workflow and link to test youtube clip could be downloaded at: https://dl.dropboxusercontent.com/u/717 ... %20mp4.zip

Hi kibi, thank you for using FFAStrans and welcome to the forum! :-)

What makes the clips incorrect? Can you please describe what you got and what you expected to get?

It seems, that it was the multithreading AviSynth issue. Had turned it off, rechecked again and found no problem. :)
Youtube-dl downloads the best possible video, and it was 4K video. That's why all the checking took so long time.

If you add some option to YouTube Decoder to set which quality to download, it would be pretty usefull.

P.S. For testing purporses I'm using a simple AVS script as input video to trim the original file to several seconds. Does any decoder processor have an option to decode a part of file?

Thanks for the good suggestion about the YouTube qualities. I'll write it down as a request :-)

The decode always decodes the whole file. Depending on the file, you might have to decode the whole thing in order to make sense of it. So having an option to decode just parts of the file is probably not very useful for generic use. Anyway, I'll will take a look at it but it wont have top priority.
