Before I dig deeper, is anyone seeing (well, hearing) the following with 0.10.0 ?
The video encoding is just fine (as it always was) but the audio 'wobbles'. It's almost imperceptible with dialogue but with a music track, I notice a pitch change for a few tenths of a second. This happens at random intervals 5-10 times per minute. This is encoding the svideo input on a PVR350. I noticed the problem after changing from: ivtv: version 0.4.8 (development revision 3527M) loading ivtv: Linux version: 2.6.15.7-PIII-061031 PENTIUMIII REGPARM 4KSTACKS gcc-3.4 ivtv0: Encoder revision: 0x02050032 to ivtv: version 0.10.0 (tagged release) loading ivtv: Linux version: 2.6.20-PIII-070218 mod_unload PENTIUMIII 4KSTACKS ivtv0: Encoder revision: 0x02060039 The only other changes were kernel config from 100Hz to 300Hz, changing the input within MythTV from svideo-0 to svideo-1 due to the V4L numbering change and switching from 'DVD-special 2' stream type to 'MPEG-PS'. Audio is 48KHz, MP2, 384Kbit as it always was: [23840.009252] saa7115 1-0021: Audio frequency: 48000 Hz [23840.011768] saa7115 1-0021: Input: S-Video 0 [23840.011807] saa7115 1-0021: Video signal: broadcast/DVD [23840.011862] saa7115 1-0021: Frequency: 50 Hz [23840.011899] saa7115 1-0021: Detected format: PAL [23840.011951] saa7115 1-0021: Width, Height: 704, 576 [23840.011989] saa7127 1-0044: Standard: 50 Hz [23840.012041] saa7127 1-0044: Input: normal [23840.012077] saa7127 1-0044: Output: S-Video + Composite [23840.012133] saa7127 1-0044: WSS: disabled [23840.012168] saa7127 1-0044: VPS: disabled [23840.012228] saa7127 1-0044: CC: disabled [23840.014360] msp3400 1-0040: MSP4418G-B3 rev1 = 0x0217 rev2 = 0x1243 [23840.014402] msp3400 1-0040: Audio: volume 58950 [23840.014456] msp3400 1-0040: Mode: External input [23840.014492] msp3400 1-0040: Audmode: 0x0001 [23840.014545] msp3400 1-0040: Routing: 0x00222220 (input) 0x00000044 (output) [23840.014586] msp3400 1-0040: ACB: 0x0c00 [23840.014639] ivtv0: Video Input: S-Video 1 [23840.014672] ivtv0: Audio Input: Line In 1 [23840.014722] ivtv0: Video Output: S-Video + Composite [23840.014757] ivtv0: Audio Output: A/V Audio Out [23840.014807] ivtv0: Output Mode: None [23840.014839] ivtv0: Tuner: TV [23840.014889] ivtv0: Stream: MPEG-2 Program Stream [23840.014924] ivtv0: VBI Format: No VBI [23840.014973] ivtv0: Video: 704x576, 25 fps [23840.015009] ivtv0: Video: MPEG-2, 4x3, Variable Bitrate, 5700000, Peak 8000000 [23840.015111] ivtv0: Video: GOP Size 12, 2 B-Frames, GOP Closure, No 3:2 Pulldown [23840.015171] ivtv0: Audio: 48 kHz, Layer II, 384 kbps, Stereo, No Emphasis, No CRC [23840.015256] ivtv0: Spatial Filter: Manual, Luma 1D Horizontal, Chroma 1D Horizontal, 0 [23840.015334] ivtv0: Temporal Filter: Manual, 0 [23840.015371] ivtv0: Median Filter: Off, Luma [0, 255], Chroma [0, 255] [23840.015426] ivtv0: Status flags: 0x00000040 Anyone else getting this? As is appears to be in the stream coming from the card, I'm thinking that it's more likely to be either the new firmware, the change to MPEG-PS or a combination of both rather than a driver issue...
