Re: File transcoded by VLC contains 20% of redundant/dummy info?

I have found what is wrong with transcoded MPEG4 file: All MPEG4 Video's P-frames contain incorrect modulo_time_base field. According to documentation, modulo_time_base field should almost always be 0, and very rarely be 1. It is said that it is almost impossible modulo_time_base to be greater than ...

Re: MPEG4 ASP transcoding issues

Hello All!
We are still unable to make VLC to transcode into MPEG4 ASP. Is there anybody who uses it here?
Is there anybody using "--sout-ffmpeg-bframes" comand line argument?
Any help or just comments would be greatly appreciated!
Thanks beforehand,
Sincerely,

Hello! I've faced a problem with transcoding to MPEG4 (see my post MPEG4 ASP transcoding issues ) and after some more in-depth analysis of resulting mp4 files I have found a bug: The resulting file transcoded by VLC seems to contain a log of dummy/redundant information. In particular, I see a lot of...
