* avcodec/cinepakenc: Fix invalid shiftsAndreas Rheinhardt2019-10-06
| | | | | | | | | | Fixes: left shift of 1 by 31 places cannot be represented in type 'int'. Affected the FATE-tests vsynth1-cinepak, vsynth2-cinepak and vsynth_lena-cinepak. Also fixes ticket #8220.

| * cinepakenc: misc small changesDiego Biurrun2017-07-05
| | | | | | | | | | | | Avoid anonymously typedeffed structs and enums, drop an unused context member, fix a small wording mishap, sizeof(type) ---> sizeof(*variable), drop a needlessly verbose log message, use av_malloc_array() where appropriate.
