After updating to the last version the browser would not open and terminal will return the error:

opera: symbol lookup error: opera: undefined symbol: av_dynamic_hdr_smpte2094_app5_to_t35

I noticed that the problem resolves if I remove the libffmpeg.so file from the lib_extra folder but then I cannot watch any video on the browser.
I tried newer libffmpeg.so but they gave error:

opera: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_ABI_DT_RELR' not found (required by /usr/lib/x86_64-linux-gnu/opera-stable/lib_extra/libffmpeg.so)

Does anyone have any idea about this?
