Zdravím.
Prepáčte mi, ale musím sa spýtať fakt dosť lamersky. Posledné dni a týždne si vtĺkam do hlavy formáty, kontajnery, kodeky, bitarate....a všličo možné aj nemožné a pletie sa mi to statočne. Skúšam to v Handbrake. Asi ho tu nik nepoužíva, ale zaškrtol som voľbu Kontajnera ako mp4. A v záložke Video Video Codec H.264(x264). Mám tu nejaký výpis z mediaInfo. Spýtam sa, či toto je mp4 formát s kodekom H.264?
