Hard to say anything specific without seeing your code or at least the encoded file. A wild guess could be missing extradata. Also, does the decoder print any errors or just fails silently? -- Anton Khirnov _______________________________________________ libav-api mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-api
