Nothing here either. > 2/ Try changing the audio output bitrate > -mpegaudio 128 Nope nothing either. > 3/ Try changing the audio sampling frequency > -f 44100 -mpegaudio 192 Still nothing. > 4/ Try combining 2/ and 3/ > -f 44100 -mpegaudio 128 > > Unfortunately I'm just grasping at straws at this point... Still nothing on those. I had updated WISInput.cpp neat line 208 to look more like gorecord for audio device selection because the I was getting an "Unable to find emulated OSS device node" message. But since I am getting pcm audio I doubt that is the issue. + char *c; + printf(line, "%d: [%u-%*u]: digital audio\n", &m, &n); - //if (sscanf(line, "%d: [%u-%*u]: digital audio\n", &m, &n) != 2) continue; + if ((c = strrchr(line, ':')) == NULL || + strcmp(c, ": digital audio\n") || + sscanf(line, "%d: [%u-%*u]:", &m, &n) != 2) + continue; Also with aac I no sound. With amr I get no sound but I also get the following from wis-streamer: RTCPInstance::RTCPInstance error: totSessionBW parameter should not be zero! And with ulaw all I get is static. Here is some sound device info from my system: #ls -ltr /dev/dsp* crw-rw---- 1 root audio 14, 3 Dec 14 17:38 /dev/dsp 3cat /proc/asound/oss/devices 0: [0- 0]: mixer 3: [0- 0]: digital audio 4: [0- 0]: digital audio #cat /sys/class/sound/dsp/dev 14:3 #cat /proc/asound/oss/sndstatcat /proc/asound/oss/sndstat Sound Driver:3.8.1a-980706 (ALSA v1.0.14 emulation code) Kernel: Linux KUROHG 2.6.23.9 #2 Fri Dec 7 13:43:42 PST 2007 ppc Config options: 0 Installed drivers: Type 10: ALSA emulation Card config: Plextor PX-TV402 Audio devices: 0: Synth devices: NOT ENABLED IN CONFIG Midi devices: NOT ENABLED IN CONFIG Timers: 7: system timer Mixers: 0: mixer00 Could this be an endian issue with the audio encoders that are currently being used? Im running this on a KuroHG PowerPC (http://www.nas-central.org/index.php/Category:Kurobox) that I have used with mythtv as regular recording device but the current mythtv support does not include mpeg2 video at the moment. Adding mythtv support for mpeg2 is out of my league, so I had hoped that wis-streamer would meet my needs. It appears that the mpegaudio.c in wis-streamer is close to an older version of ffmpeg based on the comments, do you recall when this was included? Thanks for helping track this issue for me down. -Eric _______________________________________________ live-devel mailing list live-devel@lists.live555.com http://lists.live555.com/mailman/listinfo/live-devel
