I am using bttv 0.8.46 on kernel 2.4.19 with the v4l2 and ac4 patches and 5 ATI TV Wonder cards. I am capturing mpeg 1 video at 1fps 50kbps bitrate with an audio stream at 32kbs with a custom version of mp1e. I am also trying to capture the closed caption text at the same time using the v4l2 streaming interface. After less than 20 minutes of capture I get Input/Output (5) errors when trying to dequeue a buffer, this error happens at the same time on both the cc and mp1e capture programs. I also receive a lot of SCERRs in the log file just prior to the Input/Output errors. Has anyone seen this behavior before? Does anyone know what may cause these errors (the video signal is perfect)? Are there any parameters that I can tweak to help this condition?
