#8605: DV25 flagged as progressive in AVI vprp chunk ----------------------------------+-------------------------------------- Reporter: Zenitram | Type: defect Status: new | Priority: normal Component: avformat | Version: git-master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+-------------------------------------- Summary of the bug: DV25 is interlaced (the only progressive DV are "DVCPRO Progressive" format at 50 Mbps, and DVCPRO HD), but is sometimes flagged as progressive when muxed in AVI by FFmpeg. DV --> MOV: OK (no "fiel" atom written) DV --> AVI: NOK ("vprp" chunk written with FieldPerFrame set to 1) DV in MOV with correct "fiel" atom -> AVI: OK ("vprp" chunk written with FieldPerFrame set to 2) DV in AVI with correct "vprp" chunk -> AVI: NOK ("vprp" chunk written with FieldPerFrame set to 1) First command is DV in AVI direct creation (wrong "vprp"). Second and third command are transwrapping from DV in MOV (edited for injecting a "fiel" atom, attached) to AVI (this one is OK, correct "vprp"), then AVI to AVI (this one is NOK, wrong "vprp").
