mencoder pipe into ffmpeg
What I need is for this to be properly piped
Or for mencoder to output near lossless mpeg4
mencoder *.avi | ffmpeg -f mp4 -vcodec mpeg4 -qscale 1 -s 1280x720 -pix_fmt yuv420p -qmin 1 -intra -acodec libmp3lame -ab 160k -ar 44100 -ac 2 Video-A.mov
I do a lot of video rendering by scripts for my youtube channel. Due to issues with sync I have a script with a section like this.
then does several of these
mencoder -oac copy -ovc copy -o Video-A.mov *.avi
ffmpeg -i Video-A.mov -f mp4 -vcodec mpeg4 -qscale 1 -s 1280x720 -pix_fmt yuv420p -qmin 1 -intra -acodec libmp3lame -ab 160k -ar 44100 -ac 2 Video-B.mov
With different starting (-ss) times and different names. Basically it cuts things up into episodes of 12 minutes and 5 seconds.
ffmpeg -ss 00:00:00 -t 00:12:05 -i Video-B.mov -vcodec copy -acodec copy "Video-1.mov"
Now, I find it would be more efficient if mencoder could transcode the video into lossless mpeg4 from the start. Or pipe it into ffmpeg so ffmpeg takes care of the encoding. Keeping the original encoding makes things go out of sync, the later episodes gets lots of complaints.
I've googled for a solution and also gone through the man pages of mencoder.
