avcodec : consider an error during decoder draining as EOF
2 mars 2017, par wm4avcodec : consider an error during decoder draining as EOF
There is no reason that draining couldn’t return an error or two. But
some decoders don’t handle this very well, and might always return an
error. This can lead to API users getting into an infinite loop and
burning CPU, because no progress is made and EOF is never returned.In fact, ffmpeg.c contains a hack against such a case. It is made
unnecessary with this commit, and removed with the next one. (This
particular error case seems to have been fixed since the hack was
added, though.)This might lose frames if decoding returns errors during draining.

Parsing NAL units using FFMPEG
6 novembre 2013, par 2ndlifeI am new to MPEG-4 and taking baby steps to learn it. I am using FFMPEG as reference.
-
I understand that all mpeg-4 are encoded into NAL units and wrt to FFMPEG av_read_frame() function returns one NAL unit, Am I right ? Is frame a NAL unit ? (though it can be a combination of multiple NALs)
-
I also saw that h264_parser.c implements a function called h264_parse which is calling parse_nal_units() inside, If i need to get NAL units how can I use this parse_nal_units from my main function ?
-
What is av_parse_Parse2() function do ? does it return decoded NAL units ?
-
OR FFMPEG has -vbsf h264_mp4toannexb switch to dump raw NAL units, Can somebody help me understand how I can use the same from my main function ?
Please help me out here...
