mmal-opaque: received empty buffer - Raspberry Pi Forums

hello,

try find problem in raspimjpeg (http://www.raspberrypi.org/forums/viewt ... 91#p468491) latest raspian updates (apt-get update, rpi-update done). happens while taking snapshot web interface.

after quite while of debugging found hint in vcos debug components mmalsrv, mmal-opaque , mmal set info. reference added prepending lines.
please have closer @ 2 distinct lines surrounded empty lines.

right in line before "received empty buffer" thing happens, see "pts" set negative value. don't know pts stands can assume pointer should never negative.
can point me right direction...

if need more information application please let me know. i'll try best give information needed since didn't develop application.

pts = presentation timestamp. not useful stills captures.

-9223372036854775808 = 0x8000000000000000. have in mmal_types.h , you'll find

code: select all

#define mmal_time_unknown (int64_c(1)<<63)  /**< special value signalling time not known */

ie buffer of unknown time.

combine flags 0x1. in mmal_buffer.h find

code: select all

#define mmal_buffer_header_flag_eos                    (1<<0)

buffer signalling end of image, , no further images produced.

quite normal stills captures. on triggering capture set of buffers through carrying image, , camera signals end of capture via eos flag, , won't more buffers through until set capturing parameter again.

sorry, nothing see there.
