Not sure if this post belongs here so apologies in advance.
I have read with great interest the thread on realmedia splitter (I really appreciate all the great work from everyone involved, esp. GaBest). I have been banging my head all day trying to transcode some real media files. They are basically videos of lecture sessions so I'm not overly concerned with video and audio quality as much as being able to transcode to RV9 to get smaller files sizes. At this stage I'm exploring the transcoding route because I don't have access to the original DV anymore.
The real files are encoded as follows:
512K DSL/Cable Modem (450 Kbps)
Stream 0: Audio: bitrate=64695, preroll=1840, sampling rate=44100, codec='64 kbps Music'
Stream 1: Video: bitrate=385917, preroll=2869, frame rate=25, codec='RealVideo G2'
I'm on a really steep learning curve here so bear with my noo-ness please. Having downloaded and registered the splitter I have tried the following without success:
Trial: Reading the real file into Real Producer Plus (which was stated as possible with the arrivla of the splitter/DirectShow capability)
Result: I get a green screen for input. Audio is transcoded sucessfully but there's no video.
Trial: Use a simple AVISynth script to frameserve to Real Producer Plus. Use a single line entry DirectShowSource("realmedia file",fps=25)
Result: Error: File does not contain recognized data for encoding
Trial: Read in a thread that Real Producer Plus requires YUY2 input so added ConvertToYUY2() to the AVISynth script above.
Result: Only video input, no audio. (I don't understand this because I have encoded other avi files with AviSynth scripts liek this and never lost audio.)
Trial: Caught sight of a thing called graphedit. Downloaded it. Its really great. I love the interface. When I render the real media file and play I get both video and audio playing so it seems the splitter works (lastest version btw - 1.0.0.9 I think). I even managed to output the audio in wave and mp3 formats (although I can't get it to go through the Lame encoder specifically).
Result: I can't get a video file output. I've tried sending the xformed video to Huffy and then filewriter, filedump, dump. I can't get a connection with filewriter, and filedump and dump return unrecognised data (non-video I guess). I figure this has got to be simple but I can't get it to work. I've also surfed and tried AVIMUX filter -> filewriter but graphedit just vapourises when I try to play this particular scenario. Surely this has got to be simple but I just don't get it.
The only sucess I've had is to convert to AVI (Huffy codec) with EO-video and then encode with Real Producer. Yes I can go this route but I'd prefer to get a little more interactive and use all the tools around here that you all helped develop because then I learn something along the way. I'm no programmer but, what I can give back is my experience as a user.
So I hope someone can help me to get this work. Particularly the graphedit route. I love that program (and realmedia splitter of course)
take care.
