I have a strange problem. I tried adding subtitles to my viewer using
libav filters. The code is extracted from filtering_video.c. It works
fine on Linux, but on Windows, it barfs with a bunch of errors when
parsing the filter graph. Here are the errors:
[avi] args
video_size=1916x792:pix_fmt=0:time_base=1/1000:pixel_aspect=1/1:frame_rate=24000/1001
(passed to buffersrc_ctx )
[avi] subtitles=f:/code/applications/mrViewer/sub.srt
passed to avfilter_graph_parse_ptr.
ERROR: [ffmpeg] Unable to parse option value
"/code/applications/mrViewer/sub.srt" as image size
ERROR: [ffmpeg] Unable to parse option value
"/code/applications/mrViewer/sub.srt" as image size
ERROR: [ffmpeg] Error setting option original_size to value
/code/applications/mrViewer/sub.srt.
ERROR: [ffmpeg] Error applying options to the filter.
ERROR: [ffmpeg] Error initializing filter 'subtitles'
ERROR: [ffmpeg] with args 'f:/code/applications/mrViewer/sub.srt'
ERROR: [ffmpeg]
It looks as if ffmpeg is confusing the : of the file with the colon of
different arguments. I tried backslashing (\) the : but that did not
work. If someone wants to take a look more deeply I can provide the
source code.
