TDA4AL-Q1: How to revert libavcodec

Hello. Ti experts.

I'm trying to libavcodec, libavutil in PSDK 9.0.0.2.

But it seems like some of the features are not supported such as AVBitStreamFilterContext type, av_register_all(), and so on.

It's supported in PSDK 8.6. So I found out if those things are in targets.

For example In PSDK8.6, AVBitStreamFilterContext is in targetfs/usr/include/libavcodec/avcode.h as below.

#if FF_API_OLD_BSF
typedef struct AVBitStreamFilterContext {
    void *priv_data;
    const struct AVBitStreamFilter *filter;
    AVCodecParserContext *parser;
    struct AVBitStreamFilterContext *next;
    /**
     * Internal default arguments, used if NULL is passed to av_bitstream_filter_filter().
     * Not for access by library users.
     */
    char *args;
} AVBitStreamFilterContext;

...
...

#endif

av_register_all() is defined in avformat.h as below.

#if FF_API_NEXT
/**
 * Initialize libavformat and register all the muxers, demuxers and
 * protocols. If you do not call this function, then you can select
 * exactly which formats you want to support.
 *
 * @see av_register_input_format()
 * @see av_register_output_format()
 */
attribute_deprecated
void av_register_all(void);

attribute_deprecated
void av_register_input_format(AVInputFormat *format);
attribute_deprecated
void av_register_output_format(AVOutputFormat *format);
#endif

These are in the defined option using #ifdef.

But, In targets of PSDK9.0.0.2, AVBitStreamFilterContext type, av_register_all() are not defined anywhere.

So I can't build my app which is using libavcodec.

I would like to know how to revert that libs into targetfs.

Best regards
