Hi Jose,

No that's a pity... >I am doing dvb decoding as well, and I have the problem that >sometimes, the mpeg2 decoder does not find the parameters (wxh, pixel >format etc). I saw in your previous post this flags. Could you explain >what issues did they solve? Well, I think any of the ffmpeg maintainers could do a much better job than I at explaining these parameters, but as far as I have figured it out: > gContext->workaround_bugs = FF_BUG_AUTODETECT; This attempts to detect problems introduced into the mpeg stream by known bugs in various third-party encoders (Micro$oft, etc.) AUTODETECT means that you don't which encoder was used to produce you stream, so let libavcodec attempt to autodetect known bugs. There are other flags that are third-party encoder-specific that you can use if you know that you will always be working with a specific encoder that has known bugs. > gContext->error_concealment = FF_EC_GUESS_MVS; This tells the decoder which method (there's seems to be two currently,) to conceal errors. One is DEBLOCK and the other is the GUESS_MVS, above. > gContext->error_recognition = FF_ER_CAREFUL; Tells the decoder how strict it has to be in detecting errors. CAREFUL is the most relaxed setting. HTH, Bob _______________________________________________ libav-user mailing list libav-user@mplayerhq.hu https://lists.mplayerhq.hu/mailman/listinfo/libav-user
