I am streaming audio between two linux machines using ffmpeg and ffplay. The sender is using rtsp to transport audio using a USB microphone over TCP. The receiver (listener) is receiving and playing the audio received using ffplay.
Sending: Receiving(listening): Using /‘ashowinfo’/, I am able to see a line containing various information for each input audio frame. The option /nostats/ is used to avoid other stats interleaved within the log output. “n” denotes the (sequential) number of the input frame, starting from 0. The receiver and sender are both using the /-af/ option flag to see the frame counts. However when the stream ends, the audio frame numbers are completely off as shown below. I have searched before, but have not seen any specific or technical algorithm that ffmpeg uses to justify how frame counts are defined. Also I am not sure why my sender with the microphone audio has various nb_sample sizes with each frame increment? I have noticed that the audio streamed from rtsp is always received as having each frame with "nb_sample" of 1024. I have tried adding the /frame_size/ option but with no change in consistent number of samples per frame input for the sender. The aim is to have a consist method to correlate where the sender and receiver are at once the audio stream has been stopped. Below are the log files outputted for each command with their respective machines: Sending log: Receiving log: -- Sent from: http://www.ffmpeg-archive.org/ _______________________________________________ ffmpeg-user mailing list email@example.com https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
