Originally posted by **zhoutian94** July 18, 2023 I'm trying to transcode dhav (one of the container format) to RTSP By JavaCV（FFmpegFrameGrabber + FFmpegFrameRecorder） , It's fine when i transcoding dhav to RTMP , but when I change to RTSP ,error occurred: ``` Error: [rtsp @ 0000002318df7c30] AAC with no global headers is currently not supported.

These mabay can help,about the dhav (snapshot) : ``` Input #0, dhav, from '.\videostream': Duration: 00:00:25.00, start: 1689678599.000000, bitrate: 2360 kb/s Stream #0:0: Audio: pcm_s16le, 16000 Hz, 1 channels, s16, 256 kb/s Stream #0:1: Video: h264 (High), yuvj420p(pc, bt470bg/bt470bg/bt709), 720x1280, 25 fps, 50 tbr, 1k tbn ```

ok, I figure out, just add recorder.setAudioBitrate(grabber.getAudioBitrate()); , dhav to rtsp is ok
