No, your exmple is invalid and will report error for it expects hex stringand 2 hex digits can represent 1 byte.

TF_SetConfig wants user to provide the config as a serialized protobuf string. If you turn on the print by json in the python script, that's print(list(map(hex, s))) ['0x10', '0x2', '0x28', '0x5', '0x32', '0xe', '0x9', '0x9a', '0x99', '0x99', '0x99', '0x99', '0x99', '0xb9', '0x3f', '0x20', '0x1', '0x2a', '0x1', '0x30', '0x38', '0x1'] So we use the hex string format like below so that we can use them in config easily. 0x10022805320e099a9999999999b93f20012a01303801 > > _______________________________________________ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > https://ffmpeg.org/mailman/listinfo/ffmpeg-devel > > To unsubscribe, visit link above, or email > ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe".
