Hi folks - I'm using mod_fsv to record incoming video to an .fsv file, then using ffmpeg to convert it. It works perfectly fine when the video codec is h264 or h263+. But when the video codec is h263, it creates corrupted video. ffmpeg creates a gibberish movie, and reports a large number of errors. (Pasted below). However, when play_fsv is used to play that same .fsv file back via freeswitch to my videophone, the video is clear and fine. The issue appears to be in mod_fsv's recording, fsvdec, or similar. ffmpeg is compiled with fsvdec.c Output when using h264 or h263+ is typical ffmpeg success output, and the generated .mp4 is nice and clear. Warning output from h263 spans a large number of pages, but are variations on: [h263 @ 0x3143200] illegal ac vlc code at 1x1 [h263 @ 0x3143200] Error at MB: 24 [h263 @ 0x3143200] illegal ac vlc code at 14x1 [h263 @ 0x3143200] Error at MB: 37 [h263 @ 0x3143200] concealing 396 DC, 396 AC, 396 MV errors [h263 @ 0x3143200] illegal ac vlc code at 21x15 [h263 @ 0x3143200] Error at MB: 366 [h263 @ 0x3143200] concealing 118 DC, 118 AC, 118 MV errors [h263 @ 0x3143200] illegal dc 0 at 9 16 Last message repeated 1 times ... mod_fsv documentation on the wiki states that mod_fsv is endian dependent, yet all processing is happening on the same machine. (And the fact it works just fine for h264 and h263+ is just baffling). Any thoughts?
