Anton Khirnov	c4b074676a	fftools/ffmpeg_mux_init: avoid invalid memory access in set_dispositions() This function assumes AVMEDIA_* are always positive, while in fact it can also handle AVMEDIA_TYPE_UNKNOWN, which is -1.	1 year ago
Anton Khirnov	3a89e6d352	fftools/ffmpeg_filter: restrict reap_filters() to a single filtergraph This is more natural, as all except one of its callers require processing only one filtergraph.	1 year ago
Anton Khirnov	9d44eb8af5	fftools/ffmpeg_filter: stop accessing encoder from pixfmt selection ffmpeg CLI pixel format selection for filtering currently special-cases MJPEG encoding, where it will restrict the supported list of pixel formats depending on the value of the -strict option. In order to get that value it will apply it from the options dict into the encoder context, which is a highly invasive action even now, and would become a race once encoding is moved to its own thread. The ugliness of this code can be much reduced by moving the special handling of MJPEG into ofilter_bind_ost(), which is called from encoder init and is thus synchronized with it. There is also no need to write anything to the encoder context, we can evaluate the option into our stack variable. There is also no need to access AVCodec at all during pixel format selection, as the pixel formats array is already stored in OutputFilterPriv.	1 year ago
Anton Khirnov	45035154be	tests/fate: fix mismatches between requested and actually used pixel formats	1 year ago
Anton Khirnov	037d364797	fftools/ffmpeg_filter: move "smart" pixfmt selection to ffmpeg_mux_init This code works on encoder information and has no interaction with filtering, so it does not belong in ffmpeg_filter.	1 year ago
Anton Khirnov	249bca763d	fftools/ffmpeg_mux_init: handle pixel format endianness When -pix_fmt designates a BE/LE pixel format, it gets translated into the native one by av_get_pix_fmt(). This may not always be the best choice, as the encoder might only support one endianness. In such a case, explicitly choose the endianness supported by the encoder. While this is currently redundant with choose_pixel_fmt() in ffmpeg_filter.c, the latter code will be deprecated in following commits.	1 year ago
