This has one video stream, one audio stream (AC3 5.1). Issue: When I try to encode into any format, it reports 0 channels in ac3 stream and there is no audio track in the output. I tried with directly copying the AC3 stream, encoding AC3 to AAC, using analyzeduration option etc., But, the same file is working fine when I use Handbrake, MEncoder.

I have been searching for a proper encoder from past 2 months and couldn't find a working solution. My requirement: I have several DVDs and want to convert them into MP4/M2TS/TS files with 2 audio streams (AC3 5.1 and AAC). Also, want to add watermark on the output. Tried different encoders, but nothing is working as per my requirement. Thank you for your time!" defect open normal avformat git-master mpegps 1 0
