| | | | | Make a new template file for common SEI messages - this will also apply to H.266.

| | | | | Having these together allows us to find both pointers given the address of only one of them.

| | | | | | | | Several cbs-functions had an unused CodedBitstreamContext parameter. This commit removes these. Reviewed-by: Mark Thompson <sw@jkqxz.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/cbs_h264: Automatically free SEI payload on errorAndreas Rheinhardt2019-09-241-1/+4
| | | | | | | | | | | | | If adding an SEI message to an access unit fails, said SEI message was not touched, so that the caller had to free any data associated with it that might need to be freed. But given that ff_cbs_h264_add_sei_message can simply call cbs_h264_free_sei_payload, one can easily free the content of the SEI payload. This fixes a memleak when inserting a user data unregistered string for h264_metadata fails. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* cbs_h264, h264_metadata: Deleting SEI messages never failsAndreas Rheinhardt2019-07-081-4/+7
| | | | | | | | | | | | Given the recent changes to ff_cbs_delete_unit, it is no longer sensible to use a return value for ff_cbs_h264_delete_sei_message; instead, use asserts to ensure that the required conditions are met and remove the callers' checks for the return value. Also, document said conditions. An assert that is essentially equivalent to the one used in ff_cbs_delete_unit has been removed, too. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

| * cbs: Refcount all the things!Mark Thompson2018-02-201-0/+4
| | | | | | | | | | | | | | | | This makes it easier for users of the CBS API to get alloc/free right - all subelements use the buffer API so that it's clear how to free them. It also allows eliding some redundant copies: the packet -> fragment copy disappears after this change if the input packet is refcounted, and more codec-specific cases are now possible (but not included in this patch).
