* avcodec/mpegvideo: Move MJPEG/AMV-only fields to MJpegContextAndreas Rheinhardt2022-01-04
| | | | | | | This is possible now that MJpegContext is allocated jointly with MpegEncContext as part of the AVCodecContext's private data. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/mjpegenc: Add wrapper for ff_mjpeg_encode_picture_header()Andreas Rheinhardt2022-01-04
| | | | | | | This factors the translation from MpegEncContext out and will enable further optimizations in the next commits. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/mjpegenc: Use custom close function directlyAndreas Rheinhardt2022-01-04
| | | | | | | | | | | | Currently, ff_mpv_encode_end() is the close function of the two MJPEG-based encoders; it calls ff_mjpeg_encode_close() for them which adds a check to the generic code. This commit reverses the order of this relationship: The MJPEG encoders directly use a custom close function which in turn calls ff_mpv_encode_end(). This avoids the branch in ff_mpv_encode_end() and makes the generic code more generic. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/mjpegenc_common: Move stuff only used by mjpegenc.c to itAndreas Rheinhardt2021-02-23
| | | | | | | | This allows to make ff_init_uni_ac_vlc static; ff_mjpeg_encode_picture_frame has also been made static, but it could always have been made static. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/mjpegenc: move ff_mjpeg_encode_picture_frame to mjpegenc_commonJames Almer2017-05-08

* avcodec/mjpegenc: Remove non functional huffman reallocation and error handlingMichael Niedermayer2017-02-10
| | | | | | | If this is wanted iam not against it but it must be designed to work with all cases like slice threads, and a single growing buffer does not work very well with slices. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

| | | | | | | | | Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name.
