Re: [FFmpeg-user] ffplay with Havision Makito X video encoder, H.264 stream, and "intra refresh" option enabled
Err...sample file of what? It's an encoder...a piece of hardware. I've not tried writing the TS to a file and seeing if that also exhibits the same behavior...either played back directly from the file or as a file that's streamed back over the network as UDP to be decoded and displayed by a player. Guessing that it's likely 1MB / sec or so...so maybe a few seconds can be attached as an email. I'll see what I can come up with.

[FFmpeg-user] ffplay with Havision Makito X video encoder, H.264 stream, and "intra refresh" option enabled
I'm looking for some ideas about decoding an H.264 video stream encoded by a Haivision Makito-X encoder and using its "intra refresh" option. When the option is enabled (e.g. turning intra refresh "on") the video decode is delayed by several minutes...perhaps 30 to 45 minutes...I assume because at some point the encoder randomly ends up sending out a key frame (?) which allows the decode process to begin decoding. Up until that point however there is no video. I've tried this in FFMPEG 4.2, 4.3 and also using VLCall have the same behavior. I see lots of comments about ffmpeg supporting intra refresh but nothing specific to anyone using it with other encoders, so I don't know if intra refresh is encoder specific. My question eventually ties into some ffmpeg software that I maintain that implements a "video wall"...but I don't think is directly programming related here. Thank you. --kev ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
