If we return 0, then it is considered as EOF by calling functions (e.g. avio_read). So returning 0 means: "this is end of stream" and not: "we received zero length packet, but more data may be coming" and thus the stream processing ends. I need to fix this behavior, example errors are described here: https://blog.danman.eu/new-version-of-lenkeng-hdmi-over-ip-extender-lkv373a/#comment-478 S pozdravom / Best regards Daniel Kucera. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
