I'm trying to convert an AVI file (video M-JPEG / audio PCM) to MP4 but after a while the conversion process returns loads of errors. The most common is: [mjpeg @ 0x840fbc0]Subsampling in JPEG-LS is not supported. I uploaded a small sample of the avi file (JPEG-LS_error.avi) which generates these errors. I recorded many video files with this configuration and most of them return this error. The recording program I use is iuVCR (v. 4.7.4.293)
