Hello, I'm having a strange behavior when using ffplay on linux:
I created a program that output a live mpegts stream to a fifo (a file created by mkfifo). I'm trying to use ffplay to watch to this stream, in this way: > ffplay -probesize 100k -analyzeduration 100k - < fifo_file.ts First I start this player command, then in another console I start the program that outputs the stream to the fifo file. With this setup, I have to wait about 1 minute (or more sometimes) to get the audio/video to play, BUT when I interrupt (CTRL+C) the program that write the live stream to the fifo, the entire (since startup) video start playing instantly, something like a buffer problem... Note 1: When I use the command "hexdump < fifo_file.ts" instead of ffplay, I got the usual uninterrupted hex stream flow on console, then I think that the program that feed the fifo file is doing his job properly). Note 2: I also tryed to mess with probesize and analyzeduration values and nothing helps. Note 3: When I use the ffplay option "-v debug", I got several messages like this "[mpegts @ 0x7f4fbc000920] probing stream 2 pp:2499" the last number (2499) keep decreasing at a rate about once a second, in that time, I cannot get the video, but again: when I interrupt the source side of fifo, It appears that ffplay "wakes", and show the video immediately. If I don't interrupt and wait for about one minute, the video starts playing. The console output in this case are in: http://pastebin.com/fZDWNqF5 Note 4: From above pastebin, It appears that the stream 2 have nothing useful. **** Questions **** **** Primary question: 1) How can I play this live stream faster (starting soon, without waiting a long time) **** Secondary questions: 2) How can I tell ffplay to skip/ignore the 2nd stream, or to give up this stream early ? 3) Why when I interrupt the source program in the other side of the fifo, the video starts playing immediately? Thanks in advance. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
