Most dvd players wont play dvd filesystem burned into a cd, so if you are testing with a CD-R/RW use vcd or svcd profile. > > Meanwhile, I have tried the SVCD test.

If you want to make a standard SVCD, use mpeg2enc -f 4 -q 8 (later you can experiment with -q value for optimal quality). > INFO: [mplex] mplex version 1.6.2 (2.2.3 $Date: 2004/01/13 20:45:26 $) > INFO: [mplex] File coda.m2v looks like an MPEG Video stream. > INFO: [mplex] File coda_soundSVCD.mp2 looks like an MPEG Audio stream. > INFO: [mplex] Video stream 0: profile 4 selected - ignoring non-standard > options! > INFO: [mplex] Found 1 audio streams and 1 video streams > INFO: [mplex] Selecting SVCD output profile > INFO: [mplex] Multiplexing video program stream! > INFO: [mplex] Scanning for header info: Video stream e0 (coda.m2v) > INFO: [mplex] VIDEO STREAM: e0 > INFO: [mplex] Frame width : 720 > INFO: [mplex] Frame height : 576 > INFO: [mplex] Aspect ratio : 4:3 display > INFO: [mplex] Picture rate : 25.000 frames/sec > INFO: [mplex] Bit rate : 4500000 bits/sec > INFO: [mplex] Vbv buffer size : 229376 bytes > INFO: [mplex] CSPF : 0 > INFO: [mplex] Scanning for header info: Audio stream c0 > (coda_soundSVCD.mp2) > INFO: [mplex] MPEG AUDIO STREAM: c0 > INFO: [mplex] Audio version : 1.0 > INFO: [mplex] Layer : 2 > INFO: [mplex] CRC checksums : no > INFO: [mplex] Bit rate : 28672 bytes/sec (224 kbit/sec) > INFO: [mplex] Frequency : 44100 Hz > INFO: [mplex] Mode : 0 stereo > INFO: [mplex] Mode extension : 0 > INFO: [mplex] Copyright bit : 0 no copyright > INFO: [mplex] Original/Copy : 0 copy > INFO: [mplex] Emphasis : 0 none > INFO: [mplex] SYSTEMS/PROGRAM stream: > INFO: [mplex] rough-guess multiplexed stream data rate : 4827544 > INFO: [mplex] target data-rate specified : 2788800 The target data rate is fixed by -f 4 to svcd limit but the actual bitrate of your stream is much larger. > ++ WARN: [mplex] Target data rate lower than computed requirement! > ++ WARN: [mplex] N.b. a 20% or so discrepancy in variable bit-rate > ++ WARN: [mplex] streams is common and harmless provided no time-outs will > occur > INFO: [mplex] Run-in Sectors = 78 Video delay = 46800 Audio delay = 50400 > INFO: [mplex] New sequence commences... > INFO: [mplex] Video e0: buf= 235520 frame=000000 sector=00000000 > INFO: [mplex] Audio c0: buf= 4096 frame=000000 sector=00000000 > ++ WARN: [mplex] Stream e0: data will arrive too late sent(SCR)=591000 > required(DTS)=591000 > ++ WARN: [mplex] Video e0: buf= 220298 frame=000151 sector=00000504 > ++ WARN: [mplex] Audio c0: buf= 2424 frame=000232 sector=00000074 > ++ WARN: [mplex] Stream e0: data will arrive too late sent(SCR)=1181400 > required(DTS)=1181400 > ...... > **ERROR: [mplex] Too many frame drops -exiting If you want to make a nonstd svcd with video bitrate of 4500 kbps, pass -f 5 to mplex. You can leave out -r option and let mplex compute the required bitrate, but if that fails try with -r 4900 or so. But be warned that most standalone players will not play such high bitrate svcd streams correctly.
