A suggestion: MPEG Streamclip, a free, no further updated application, plays some'avi' movies in a hacked Yosemite, while VLC and other players only give the soundtrack. If this suggested player doesn't work with a certain 'avi', the HD player, part of the P2P application 'Vuze' always does in my experience. Output formats: H.264/MPEG-4 AVC, H.265/HEVC, MPEG-4, MPEG-2, Theora, VP9, and VP8. One of the best free video converter currently available has to be HandBrake. This is a professional video converter program that can output videos from multiple video formats (MP4, MKV, AVI, TS, M2TS), as well as digitize Blu-ray and DVDs to MKV, MP4, and WEBM.
