  • avformat/oggparsevorbis : Use AV_DICT_DONT_STRDUP_VAL to avoid av_strdup

    11 novembre 2019, par Andreas Rheinhardt
    avformat/oggparsevorbis : Use AV_DICT_DONT_STRDUP_VAL to avoid av_strdup

    This will likely also fix CID 1452427, a false positive resulting from
    
Coverity thinking that av_dict_set() automatically frees its key and
    
value parameters (even without the AV_DICT_DONT_STRDUP_* flags).
    

    (AV_DICT_APPEND and AV_DICT_DONT_STRDUP_VAL are compatible with each
    
other since a8c5b455, so we can reset this flag here. It has originally
    
been removed in 0dc66553 when appending was added.)

  • avcodec/decode : stop trying to initialize palette values in avcodec_default_get_buffer2()

    2 mai 2021, par James Almer
    avcodec/decode : stop trying to initialize palette values in avcodec_default_get_buffer2()

    avpriv_set_systematic_pal2() is meant to fill fixed vales for formats that
    
until recently were tagged as "pseudo pal". This is no longer the case, so
    
this call is a no-op when used on real PAL formats.

  • how to convert RTPDUMP video file to mp4

    2 mars 2017, par Asain Kujovic

    Viber recently got "instant video message" option, called also "video push-to-talk" (vptt).

    Inside viber data in directory ".vptt" there are files with vptt extension. Envelope format is classic ZIP file, when extracted gives jpg-thumbnail and ’video’ file.

    Video file says "# !rtpplay1.0" inside first line, so it should be format of rtp-tools, used by wireshark too, and somehow related to actual WebRTC trends...

    So if video content inside this rtpdump file is not encrypted ( ? ), "how to save viber instant message push to talk video" boils down to just : "how to convert rtpdump video to mp4".

    rtpplay can send it to some port, but ffmpeg/ffplay/vlc needs correct sdp file.

    does someone knows something further about this ?
